Hi David: I know this is an old post, but I am still having the read pixel error for my study. And I am trying to think of a way to inform the participant if their browser will work as soon as they open the study, so if it doesn’t work, they can return the study with minimum time wasted. So I have messaged one participant who had the issue with the read pixel test link that you posted here and surprisingly his browser passed everything. And the Chrome Version is 80.0.3987.106 (Official Build) (64-bit), which is pretty new. Now I am confused, he shouldn’t be having problems if his browser passed the test, right? Any ideas?
Thanks in advance.
