Audio/video not working while join from iOS app


I have setup own Jitsi server and create web app as well as iOS app. now when I Join from iOS app and then join from web in same meeting some time audio/video not working.

Specifically when I join meeting from iOS app first and then join from web by video off/audio on. I can see audio muted in iOS app even I unmute from web.

When all the users join meeting from web always working fine.

Any help will appreciate.
