Repro steps: 1. Go to https://webrtc.github.io/samples/src/content/peerconnection/pc1/ on iOS 15 2. Click "Start". Observe that you can see yourself. 3. Click "Call". Observe that remote media works and you can hear yourself. 4. Receive an incoming phone call 5. Observe that the call is now broken, and the page still says it's capturing. Impact: All WebRTC services not implementing some kind of hacky workaround. This should just work. Workaround: Possibly have a dedicated "play" button that literally no other WebRTC supporting device or video call service has ever needed, which will confuse users and provide bad UX for something that should just work. Really just the exact same thing as https://bugs.webkit.org/show_bug.cgi?id=230536, but I wanted to have two explicit bugs about this. 1795582 1 webkit-bug-importer 2021-09-21 08:56:23 -0700 <rdar://problem/83353764> 1799242 2 youennf 2021-10-01 05:31:41 -0700 Thanks for the report, I agree all 3 reports are probably tied to the same issue. We are looking into it. 1806798 3 joma 2021-10-20 13:19:17 -0700 Any updates on this? Our team is also currently facing these same issues that our workarounds are no longer fixing. 1823923 4 daginge 2021-12-14 00:34:59 -0800 I can confirm this now works as expected on iOS 15.2. Marking as resolved. Again, thank you youenn! 1860008 5 shivanagolajay 2022-04-09 04:47:14 -0700 @daginge@confrere.com we are able to reproduce this issue on ios 15.3.1 1874494 6 bodyahnedko 2022-06-07 07:23:55 -0700 Reproducible on IOS 15.4.1 @daginge@confrere.com
