SOLUTION:
Use an unofficial client:
This browser is no longer supported.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
Besides the obvious issues with M$ Teams being a horrific rip-off of Skype, outdated (compare to Discord or Slack), slow, buggy, bloated, etc. M$ Teams worked "fine" for the most part, at least to be functional enough to use in a corporate setting. At least up until about a few months ago, a lot of critical features broke when an update was pushed to the M$ Teams desktop client for Linux and made scheduling a meeting impossible. The scheduler UI is completely broken and same goes for pop-out chats among other issues, such as chats not loading and sometimes requiring the client to be restarted completely. Now M$ states to use Teams as a PWA, what the heck is a PWA?
Kindly note that this forum mainly focuses on general usage issues and is not the suitable place for feedback.
If you would like to submit feedback to Microsoft, please consider posting in the Teams feedback forum.
Thanks for your understanding.
What happened to the electron desktop app?
Teams for Linux desktop application has been retried in December, 2022.
Where do I get this PWA?
Please refer to this link to install PWA version (you may need to use Edge or Chrome browser): Microsoft Teams progressive web app now available on Linux
Does PWA support video sharing and all the current features the desktop app has?
Currently PWA does not support all the features like desktop app (if you mean desktop app for Windows).
I'm only interested in hearing from M$ developers who can resolve this issue.
