Hey, we haven't been able to reproduce your bug so far.

We tried tested it with different devices (iPhone 13 and SE), codecs (h264, vp8), and FPS (30, 60) without reproducing the behaviour you are having.

Have you tested it with another iPhone?
Is this happening consistently?
How mediaStats look like?
Do you have simulcast activated?

Maybe this information can help narrow down your problem.

Thanks in advance!

yes in iphone 13 we do not have the problem, it seems to be on iphone 11. can you please try with an iphone 11?
BTW it should happen on all iphone 11 and maybe some lower version that upgraded the system to v15+

We don't have an iPhone 11. But we we were able to reproduce it with an iPhone SE.

It may be probable that the bandwidth for the video being published is getting limited with Default configuration for this device and this iOS version (we need to run some more tests in order to confirm this).

We will keep you posted and will try to look for a WA for this issue.
