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...

Our church does a livestream each Sunday.  Our ceiling collapsed and we were forced to move to an alternative location.  We are not able to use our original AV equipment in our new space so I purchased a 20x PTZ camera from amazon, hooked up to our laptop, started a zoom meeting - got a great still picture, but movement was choppy. Figured was the Wi-Fi not having enough bandwidth. Had Ethernet run to the laptop and the choppiness issue was not resolved. People moving are not smooth, but look robotic.  This was not the case with our other system which has Black Magic hardware.  Are there some settings that need tweaked in Zoom in order to resolve the choppy livestream, which wasn't there before or does anyone have any suggestions?  This is a temporary solution for 6 to 9 months until our space gets repaired so just looking for simple fixes to get us through this period.
