The problem is only on these three devices - iPhone XS, XS Max, XR.
On all other physical devices (iPhone 5s, some devices on Android) on which I test - video conferences work fine.
After I go to the video conference screen, I immediately see that the conference terminated and see a black screen and this error:
Optional([AnyHashable(“url”): https://media.doctorsmart.ru/2383#config.startWithVideoMuted=false, AnyHashable(“error”): ])
I understand that the problem is most likely on the my Jitsi server instance.
Please tell me what could be the problem.
