This evening issues

Hi all, this evening I faced more issues during a meeting with 10 people more or less:
1- using the same link we used in the past weeks, someone connected to a different room, even if the link was the same. Then people in the same room randomly had issues of video/audio
2- after migration to a new room, issues decreased but sometimes someone disconnected and 1 or 2 times all people stopped to send video and audio, situation recovered after some seconds.
