A problem where the ATC's audio becomes inaudible when a phone call comes in while you are in contact with ATC

Device:iPhone17
Operating system:iOS26

Towards the end of my flight, while making contact with the approach, I received a phone call from a friend. After finishing the call and resuming the flight, I experienced a problem where the ATC audio was no longer audible. Since I was using AP+, clearing the cache and resuming the flight took over 30 minutes. Is this a bug, or is it a problem with my device? I was using the beta version.

It’s a bug.

sounds more like an audio routing or session handling issue on iOS than anything specific to the sim itself, when a phone call comes in iOS temporarily takes full control of the audio session and switches output modes. In some apps (especially beta versions), the audio session doesn’t always reset correctly after the call ends, so things like ATC or in-game voice can stay muted or stuck in a “background” state. Try these maybe it will fix it by restarting the app (or audio subsystem), reconnecting audio output, or fully restarting the device if it persists.
