Using the web (JS) version of opentok 2.14.8 with H.264 video codec in a relayed session. I am used the opentok reactJS accelerator sample app as the base.
Currently the allow access to camera/audio popup works well on Android (Chrome), PC/Mac (Chrome/Firefox/Safari). Note that I manually trigger a button to get access to the camera and show the feed.
When trying to access camera on iPhone/iPad I grab this error.

How can I force the 'access to camera' popup on iPhone/iPad? Note: I have tested the https://safari.opentokrtc.com/ on the same devices and they work well.
My guess is that you are setting the resolution to a low value like 320x240. There is an issue where iOS cannot give this resolution. https://bugs.webkit.org/show_bug.cgi?id=176349
If you update your code to use 640x480 instead for iOS you should be OK.
