I assume it’s no general problem as I’ve already successfully used https://f-droid.org/packages/org.jitsi.meet app version 20.5.0 for meetings. Phone is running with 0.11-q-2020090772203-dev-FP2.
I had the same symptoms with Jitsi meet on stock ROM of my FP3. Back then it was the Blokada app. I had to exclude Jitsi from being controlled by Blokada to gain access to video and audio.
Thanks for the feedback. I suspected also blokada and tracker control. But they are not the cause. Jitsi is working in the browser though. As soon as possible I will test jitsi with somebody else. It appears that jitsi is working on my e phone but not on the stock android from Samsung.
Have installed and tried Jitsi Meet on FP3 with e/os a few days ago. Downloaded from aurorastore i think. Works without issues. Does it matter where its downloaded from?
@Ingo_FP_Angel seems you were right. First I only checked if blokada blocked something. Nothing was shown in the list. This time I deactivated it. Now it is working. Trackercontrol isn’t causing any trouble.
The odd thing is: jitsi in browser & blokada works but jitsi app & blokada does not.
