Audio/video conferences on mobile app

Hi everyone,

We have a rocket chat server running, and most features are working fine.
The problem we have is related to audio/video conferences on mobile app (version 4.6.4). When joining a video call, there is no sound. Are there any setting I haven’t found that block the audio? We are using a VPN to connect to the server, and messaging works ok.

I have a BigBlueButton server, so I tried the BBB integration. It seems to work on web and desktop clients, but I don’t see any options to join or start a BBB meeting on mobile. Is BigBlueButton working for anyone else on mobile?

Any guidance would be much appreciated.
