I'm trying to join a meeting (The second part; the first was yesterday, obviously with another ID) but it's impossible with my Mac (but with Iphone it works good). The message is "you have been removed by the organizer", but it's not true 

Thank you

When someone joins my Zoom meetings it usually tells them the meeting was scheduled in the past at the time I created the meeting. I schedule meetings through the Microsoft Outlook calendar using the Zoom plugin. Wondering if this has something to do with it. I'm also on a Mac. Does anyone have suggestions on how I can fix this problem?

Greetings of the day..

I had got a link to join a webinar, i joined in from the link. In mid of the session during lunch break, that i had got disconnected from the webinar. Tried to join from the same link but it shows "INVALID LINK". how is it possible that link becomes invalid even after a certain period of time.

Is it some kind of temporary link that's created that logs you out of the webinar after duration or is it technical glitch. 

During the meeting, we hear distorting, static hissing noise if one of the participant does not mute herself. The participant is using a Chrome Book. We need her to muted herself during the meeting. She can only unmuted herself if she want to talk. What is the problem?

i am using zoom from last 3 years or so from by desktop with lenevo 300 fhd webcam. the problem is with my voice it works well, but when mic is exposed to a good blue tooth speaker the sound distorts or stop being reproduced to the participants. what is to be done. Even sharing a computer sound via youtube is also fine sounds good. the problem is with speaker when kept close to the mic to play. it becomes a mess. pl. suggest some solution. could it be webcam issue...
