Hi there, I’ve been using this library for the quite a while now with no problems.
As of late something quite strange has happened. When in a call I can share video tracks perfectly without fail but when I go to share audio to another device I get nothing.
So a step by step reproduction of this:
Answer incoming call triggered by android ( everything works fine on android ).
Attempt to share audio tracks back to Android caller.
And we get nothing.
Android build of same app can send audio & video perfectly.
The same code has always worked & still does on android, if I upgrade my phones version to iOS 13 or greater the audio tracks work again. Quite confused as to what is has happening & would appreciate any help, been scratching my head for a while on this.
Additional Info:
React - 16.8.3

Can you paste the SDP exchanges you get in both cases?
The initial Offer from iOS to another device SDP:
"v=0http://www.ietf.org/id/draft-holmer-rmcat-transport-wide-cc-extensions-01 http://www.webrtc.org/experiments/rtp-hdrext/abs-send-time http://www.ietf.org/id/draft-holmer-rmcat-transport-wide-cc-extensions-01 http://www.webrtc.org/experiments/rtp-hdrext/playout-delay http://www.webrtc.org/experiments/rtp-hdrext/video-content-type http://www.webrtc.org/experiments/rtp-hdrext/video-timing http://tools.ietf.org/html/draft-ietf-avtext-framemarking-07 http://www.webrtc.org/experiments/rtp-hdrext/color-space
Another thing to note was that we tested out the same functionality using this example but via the browser -> https://webrtc.github.io/samples/src/content/peerconnection/pc1/
Open safari on the effected device and connect to the example, video tracks share but audio dont same issue as I’m seeing in my app. Tried with other devices 13+ and it worked fine, I think the problem we are seeing could be related to the Safari version ?
Doing the above test, In Safari when get no feedback from the audio we don’t see any info, but If we run the same test via google chrome we see and error message - “getUserMedia() error: TypeError”
Also aside from this every release we have submitted to the AppStore returns a warning about the UIWebview being deprecated, does this utility not house the getUserMedia function ?

You need to send 4 SDPs: sender and receiver, both when it works and when it doesn’t. Otherwise we can’t see the whole picture here.

This is unrelated. Safari uses a different WebRTC implementation, which no longer supports plan B. Also, this plugin doesn’t use UIWebVIew, so the warning is unrelated to this.
