MS Teams is the buggiest thing I have ever had the misfortune to use. I have to log in daily to use it – the browser is a better option than the standalone client as it's easier to wipe everything and start again. Yesterday, I received the following errors during two meetings:

1) I was unable to login in Chrome – "An unexpected error has occurred"

2) In an incognito mode browser window, I was unable to login due to not permitting the use of 3rd party cookies, despite whitelisting those in Chrome's preferences

3) I wiped cookies all cookies and tried again in a normal window – I was able to log in, but when trying to have a call, I was told "This feature is only available in Google Chrome or Microsoft Edge". I was using Chrome.

4) I therefore swapped to a chrome-based browser that spoofs its user-agent as the previous version, Iridium.

5) This enabled me to start a call. It worked fine, but during the process of the meeting, the mute/video/screensharing/leave bar completely vanished, leaving a black box at the top (and me unable to mute myself or share my screen)

6) During the next meeting, about 30 s after the end of the previous one (I refreshed the page to get the box back), the camera periodically turned off with the message "Your video isn't working. We couldn't access your camera".

7) I have previously emailed M$ support highlighting these issues. The response I received was "We are aware that Teams isn't perfect and are working hard to improve it continually".

It's not fit for purpose.

Its absolutely a piece of trash software that needs to be open sourced so it can be better. My hatred for MS teams is insurmountable. Its buggy, slow as fuck, very sluggish, takes up a shitton of my resources and RAM. I hate MS teams with a passion.
