Hi all,
I've just updated my server and use the iOS client to test.
I have also checked that it's not an issue with permissions.

The problem is that with iPhone while having Push to Talk forced to you. You can still have Voice Activation. Therefore the permission is not working on iPhone.

I've also tested the same with Android, this is working as intended.
Same goes for both Mac and PC.

I hope I hear from you soon with a fix.

Kind regards,
