When handling group requests, no matter how many there are, the screen constantly loads and jitters when you scroll down to the bottom of the list. I’ve confirmed this on Chrome (85.0.4183.121 (Official Build) (64-bit)), both Windows 10 and Chromebook.
It doesn’t appear to do this on Edge, but I will test once some more requests build up.
Edit: Yes, it does on Edge, though I had to scroll to the bottom a bit to trigger it.
