 * Hi [@cukup123](https://wordpress.org/support/users/cukup123/), I’m sorry to hear
   you’re seeing this issue. We are investigating this [here on GitHub](https://github.com/woocommerce/facebook-for-woocommerce/issues/1777).
 * So far, this is the information we’ve heard back from Facebook on the issue:
 * “​… this problem seems to affect only ip_address and user_agent parameters for
   two specific events. As we’re not seeing this issue widespread across the platform
   and this problem is affecting only a small amount of events from this Pixel, 
   the problem may be due to users having ad-ons to their browser to avoid submitting
   information to websites. I recommend reviewing Pixel Settings and the code on
   the website itself to check for any issue. If there are no issues in the parameters
   requested on the website and the code is correct, please run a test using the
   test event tool. The admins may go ahead and click Mark as Resolved to see if
   the issue persists.”
 * Please try the following troubleshooting steps:
 * – check your pixel is connected
    – test using an incognito or private browser
   window with no browser extensions – its likely related to browser extensions 
   blocking user agent and IP address – enable debug logging (under Marketing > 
   Facebook) and see if you are getting any errors with more information.

 * Hi, [@cukup123](https://wordpress.org/support/users/cukup123/)! We haven’t heard
   back from you in a while, so I’m going to mark this thread as resolved. However,
   we’ll be here if/when you’re ready to continue.
