now the transcription is work when i click CC button.

But when i turn on transcription in more than 1 participant, other participant is blank with no sound and cam. this error appear on other participants too. as attached.

And this is the console log


UPDATE
I confirm that is mobile jitsi bug, because i join the room with mobile apps. It’s no bug if i join with browser
