Our team is developing chat application with 1-1 and group calls. We came upon an issue that when we are on active call, and so we have active audio stream, and I can hear everyone, and everyone can hear me. But when I get a call from another messenger, for example Skype, I lose my audio stream on iOS, neither I can hear anyone, nor anyone can hear me while I have notification from Skype. But even when I swipe it away, I can not hear anyone, looks like I lose my audio stream, or another app takes it away.
Does anyone have an idea why this is happening and what to do with it?
