same situation here. on I'm on 16.1 now and it's happening systematically. In my case, it's occurring after a network call which triggers the collectionView to reloadData. If I comment out the collectionView.reloadData(), the cells appear properly. Did you end up finding a fix for this?

Hi there, I’m curious if you manage to find a solution to this issue. I’m facing something similar and debugging has been pretty much hit and miss for the last two days. Any insights might help.
