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.

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?
