Unfortunately, I cannot run my experiment online. I get an Unspecified Javascript Error, exactly the same as I described [in the first part of this post](https://discourse.psychopy.org/t/unspecified-javascript-error-possibly-something-with-getting-framerate/15641). It has to do with the function _requestAnimationFrame_. Removing requests for frame rate results in the same errors as reported in the added section of that post.  
Going back to 2020.1.3 is now no longer an option either.
