We manage a coworking space and our members have reported issues when trying to use Zoom in our office. Their calls lag by a few seconds, cut in and out and become impossible to host. Could the issue be that multiple users are trying to host calls at the same time from the same IP address? Thanks!

Like the subject says. 

Without the native window frame I can't access window manager controls like "this window visible on all workspaces".  Once upon a time Chrome did this, too, but allowed the native window frame to be enabled via Settings. I can't find any such in Zoom settings.

Any workarounds?

I use Zoom on both devices Window and Mac. While using zoom on windows we share one screen and we can check other screens without interrupting sharing. But when I start doing it on Mac screen sharing is interrupted until I have the shared window opened on my screen So is it possible on Macbook?

My laptop has two screens and two people are successfully sharing with me but I can only annotate on one screen.

Two screen annotation has been working for 5 years and suddenly stopped working - any ideas?

A second device allows second sharer annotation but I used to be able to do it from one device.

I can setup my Zoom meeting, but I cannot invite anyone. Each time I click Invite, the Outlook invitation appears momentarily, but then Outlook crashes. Previously, I have scheduled many Zoom meetings and I can write emails on Outlook, no problem. I have updated both Zoom Workplace (Version: 6.1.11 (39163)) and MS Outlook for Mac (16.89.3 (24092813)). I have restarted the computer. My prospective client is expecting the Zoom invite now. Hoping I do not lose this prospect. Can anyone help? Thank you.
