Hi @desouky , I have seen this issue shared by another customer as well. Could you please message some of the meeting/webinar ids? Additionally, did all participants experience the same audio/video quality lag? Gianni ---

Hey @desouky, Thanks for following up with us! I checked our logs but wasn’t able to see any cause that would affect all the participants. I’ve since reached out to our engineering team to see if they can offer insight here. I’ll let you know what I hear. (ZSEE-37225) Thanks, Max ---

Hey @desouky, Thanks for following up on this. In regard to the initial issue, are you able to provide timestamps for when you’ve seen this? Are there any other meeting IDs that exhibited the problem? For the second issue, are you saying that when attempting to start an instant meeting with the Web SDK it doesn’t register the attendees correctly? Does this happen every time you use an instant meeting? Thanks, Max ---
