 * Hello,
 * I have several websites, in some of them, the ads are inserted on the theme.
 * I have this plugin since 5 or 6 weeks ago. I have thousands of 2.1 error. Yes,
   google adsense is appearing before the user accepts, the ads are not being blocked.
 * I have noticed dozens of sites, at least the Portuguese ones, and very few are
   working correctly, with the privacy popup blocking adsense first.
 * I read the post “Google IAB TCF v2 Error Codes & Guidance” but I didn’t understand
   it. I believe many, many, many site owners are with the same problem as me.
 * What should I do?

 * Hello, all.
 * I got same message from Adsense (error 2.1a) just after trying to implement the
   Quantcast GDPR pop-up. I had the Ultimate GDPR plugin for several years and nothing
   was ever popping up in adsense.
 * I couldn’t deal with Quantcast product despite sincerely wanting to understand
   all the tutorials – ads were not blocked before consent, so I went back to the
   old plugin further. **Unfortunately, the message on Adsense does not disappear
   for 3 days and I noticed a drop in earnings, should I worry about it? **
 * So Quantcast at the end, thank you so much for the noticeable drop in my earnings
   and the stressful message from Adsense.
 * I am asking you to come up with some simple solutions. I can do a lot, but it
   is too much for me, and the more ordinary user will not be able to cope with 
   it completely.
 * Greetings,
    Miłosz

 * Crougle, yes, you should be worried! I have that problem for almost 8 weeks. 
   The ads are not blocking before consent and the earning droped consideraly.

 * Thx son_gokou for the quick reply. I’m a bit scared, because I’ve already returned
   to the old plugin, where adsense had no problems with it. The plugin completely
   blocks the ads before giving consent. But this plugin unfortunately does not 
   work for TCF v2.0. Probably if I hadn’t changed it to Quantcast, no message would
   have come up. And now I am forced to step into TCF v2.0 by this message, but 
   how, and how much time do I have left? – I have no idea.
 * I read in the Google Adsense regulations that from October 16, Google will implement
   their own cookies. Does anyone know how it will work? Will their own opt-in popup
   appear on my website? And the problem with this stressful message will be solved?
 * Anyone know of any simple alternatives to Quantcast to implement GDPR with the
   new requirements? Because I can see in the forum here that there is nothing to
   count on for help from Quantcast.

 * hi, i’ve the same problem and QC is not anwering at all.
    the only solution that
   i’ve found (working) is Iubenda, but you need to be ready to spend (free up to
   25Kpageview per month….). unfortunately seems that no free plugin exists….

 * Quantcast choice doesn’t block ads. You need to use one of Adsense inserting 
   plugins, like Advanced ads, or Ad Inserter. Adding your Adsense codes in these,
   you will have the ‘power’, to prevent ads from loading, before user gives his
   consent and those plugins will communicate with Quantcast Choice. If user accepts,
   ads will show, if user denies cookies, ads will not show. Else, Google won’t 
   show ads if there’s no reply sent from user, through Choice form. You have an
   entire thread here on how to setup both. Check for pinned posts.
 * It basically goes like this, when you setup everything properly: user loads your
   website, Quantcast Choice pops up in the middle of the screen. Ads are not loaded
   in background. IF user gives his consent, settings are saved, Ads are loaded.
   If user doesn’t give consent, no ads will be loaded.
