Can't launch or log in to Zoom from MS Edge

[matta351532]

I am using a Windows laptop with Microsoft Edge. I'm not sure why this is a new issue, but I can't seem to use the browser to sign in or launch meetings from Outlook. I use my school's SSO which directs me to sign in on the browser, but there seems to be the issue of the browser not being able to communicate with Zoom. It works the other way around, where signing in opens the browser, but not the browser to Zoom if that makes sense. I can't click on "Launch Meeting" buttons and I am forced to join via browser. I know the browser used to ask if it should always launch Zoom without needing to ask, but even after resetting my browser settings, it still doesn't communicate with the app. I can't sign in to the Zoom app and I can't join any meetings that require me to sign in.

I don't have this issue on any of my other windows devices, so I'm quite puzzled with this issue.

I'm having the same issue on the Mac. SSO login to Zoom works but I'm not prompted, nor does it launch the Zoom Workplace app.
My browser is up to date. 
I also tried Google Chrome and Safari, and the Zoom workplace app didn't launch. 
I updated Zoom workplace - no luck.
I uninstalled Zoom workplace and deleted the Zoom cache and reinstalled it - no luck.
I checked all the settings on the Mac - they look fine, and permissions haven't change. 
The last update to the Mac was weeks ago. 
This problem started right before the I updated to the latest version of Zoom. 
Since the website isn't prompting me or send back a signal I wonder if that is the issue? 
For now, I will use my browser to launch meetings.

Looked like there was a little update this afternoon. Still doesn't work correctly for me. 😞

I solved my issue by uninstalling Zoom and downloading it again. For Mac, maybe visit here? Solved: Zoom join links don't open app on macOS - Zoom Community, though you did mention the issue applies to all browsers, I don't use a Mac so I'm not too sure, maybe try booting into safe mode and try to join the meeting. If that doesn't work, maybe try using AppCleaner to ensure that all residual Zoom files are deleted before downloading again?
