Thanks for providing some details about the issue you see (or not in this case). Can you provide some of the code you’ve used to display the participant videos in your app? Have you noticed this issue after upgrading - and if so, have you tried returning to a previous version?

The Video SDK also has a new release v1.6.2 - I know a few things were fixed that may solve this issue as well. Let me know if that helps.
