Talk Android app, microphone is disabled

Nextcloud version (eg, 24.0.1): 31.0.5
Talk Server version (eg, 14.0.2): 21.1.0
Custom Signaling server configured: no
Custom TURN server configured: no
Custom STUN server configured: no

In case mobile Nextcloud Talk apps are involved:

Talk Android version (eg, 14.0.2): 21.1.0

The issue you are facing:

I get a pop-up message that microphone is disabled (see attached screenshot)
When I call another user (on iOS) I can hear them but they don’t hear me.
I did all of following to fix, without success:

  • Checked Microphone App Permissions:
    Talk is allowed to use microphone
  • Disabled Battery Optimization.
  • Checked Mute/Unmute Button.
  • Restarted the App and Device.
  • Tried Push-to-talk, as suggested by screenshot, no luck.

Other thing I have tried:

  • Remove account from android app, clear app cache and re-initiate account.
    No success.
  • Totally uninstall app and reinstall from Google app store (Not F-Droid)
    No success.

Only thing I can think of is that, in windows web browser, I have enabled:
“Turn off camera and microphone by default when joining a call”
later when I realized what I did, I disabled it, but android app might be stuck in that status.

To test from my Android phone, I initiated call from within Firefox browser ( https://MyNextcloud.url) and everything worked fine, there was no microphone issue.
So something is wrong with android app, is it a bug?
