Video in safari on Iphone works kindoff

I am using the latest version that’s on Github, not the stable version. Interestingly video on iphone using Safari works , but the video swicthes off after 3-4 minutes audio is on , the person on iphone can see the other people and hear everything and others can hear the iphone user but cant see him. Sometimes the person gets an error saying cannot access camera , sometimes there is no error message.

The question is : Is this a planned feature and needs some finetuning to make it fix the problem of video getting switched off?
