 * Hi,
 * I recently updated HD Quiz to the latest version. Before the update, you provided
   me with the following code to automatically start the quiz after a few seconds
   because some users could not find the Start Quiz button:
 *     ```wp-block-code
       function hdq_mehdis6211_init($data)
       {
           array_push($data->hdq_init, "hdq_mehdis6211_after");
           return $data;
       }
       add_action("hdq_init", "hdq_mehdis6211_init");
   
       function hdq_mehdis6211_after()
       {
       ?>
       <script>
       function hdq_mehdis6211_after(){
           const sel = document.getElementsByClassName("hdq_quiz_start");
           if(sel.length == 0){
               return;
           }
           setTimeout(function(){sel[0].click();}, 1500);
       }
       </script>
       <?php
       }
       add_action("hdq_after", "hdq_mehdis6211_after");
       ```
   
 * Since updating to the latest version, a small number of users have reported that
   when they click the “Start Quiz” button, nothing happens and the quiz does not
   begin.
 * I have tested the quizzes myself on multiple PCs and mobile devices, and everything
   works correctly for me. However, the users who reported the issue were using 
   older Android versions (Android 9, 10, and 11).
 * Could you please confirm whether this custom auto-start code is still fully compatible
   with the latest version of HD Quiz? Has anything changed in the quiz initialization
   process or the `.hdq_quiz_start` button that could cause issues on some devices
   or browsers?
 * Thank you.

 * Hi mehdis6211,
   that code should still function without issue.
 * It’s not just HD Quiz that had a recent update, but the WordPress core itself
   to the new `v7`.
 * Right now my theory is that because this is only happening on older devices (
   thanks for providing that info!), the code is working, but is taking too long
   to run if there is a bunch of other stuff that needs to happen on your site first.
   Another possibility is that those devices are so old they are not compatible 
   with WordPress’ security NONCEs being fetched.
 * There are two things you can try.
 * The first is to do a very small edit to `./hd-quiz/assets/frontend/hdq_script.
   js`
 * On line `6` you will see `HDQ.nonce();`. All you need to do is to move that to
   the end of the function, just after line `36` `HDQ.kb();`. This will make it 
   so that if I’m right that those older devices are unable to fetch a nonce, the
   quiz will still work and load, but be unable to send data anywhere after (example:
   save results light, or the Secure Answers feature).
 * Try this first, clear your site cache, and see if reports still come in.
 * If the issue is simply that your site is taking too long to load for these older
   devices, there is little I can do on HD Quiz side since your users would literally
   be waiting for something else on your site to load before HD Quiz can begin loading.
   This issue would be this: start quiz button isn’t clickable until HD Quiz has
   loaded. If you have a script earlier on the page (such as an ad script or something)
   that takes a long time to load, because it is loaded higher on the page, it prevents
   HD Quiz from loading until it completes.

 * Hi,
 * Thank you very much for your support and for taking the time to investigate the
   issue.
 * I applied the change you suggested by moving `HDQ.nonce();` to the end of the
   init function, cleared all caches, and tested the quizzes on several devices.
   Everything is working correctly so far, and I haven’t received any new reports
   from users about quizzes not starting.
 * I really appreciate your help and the detailed explanation. Your support has 
   always been excellent and it helped me troubleshoot the issue much faster.
 * Thank you again for your time and assistance!
 * Best regards,
   Mehdi

 * Great! Fingers crossed this fixes the issue for you.
 * I’ve just updated the plugin with this change in case anyone else has a similar
   issue, and so that you don’t need to redo the change every time you update. I
   didn’t do a “version bump” so for any other users reading this thread, you will
   need to reinstall HD Quiz to get this change if using `v2.2.1`

 * Hi Dylan,
   I wanted to give you an update after testing the change you suggested.
   I applied the modification, cleared all caches, and monitored the site for several
   days (approximately 3–4 days). Initially, everything seemed fine, and I tested
   the quizzes on multiple devices without any issues.However, I am still receiving
   occasional reports from a small number of users that the quiz does not start 
   when they click the “Start Quiz” button.After investigating these reports, I 
   noticed a pattern: the affected users are all using older Android devices. For
   example, today I checked a user’s device and found they were running Android 
   8. Previous reports were also from devices running Android 9 and Android 10.To
   verify this, I temporarily rolled back HD Quiz to the previous version, and the
   affected users reported that the quizzes started working again.At the moment,
   it seems that something introduced in the newer version may be causing compatibility
   issues with older Android devices, while newer devices and desktop browsers continue
   to work normally.Unfortunately, because my website is used by a large number 
   of driving license students, I had to revert to the previous version to avoid
   further user complaints.Do you have any ideas on what else could be causing this
   issue specifically on older Android versions? If there is any debugging information,
   console output, or testing you would like me to collect, I would be happy to 
   help.Thank you again for your continued support and assistance.Best regards,Mehdi
