Deeply saddened but not surprised.
I had teams on this machine but it wouldnt let me log in, despite having been registered for over a year with microsoft 2 factor auth it insisted I did it again. I tried and managed eventually after going through dozens of possibilities to find where I could scan the QR code (surely to **bleep** this should be front page news?) then the web page told me I had to enter a number on the phone app, I did. I entered it correctly, the 'yes' then showed as black and I pressed it. The web page then said I had said no and had to send the number again. I tried again... failed... I have tried it for two days after reporting to MS they have **bleep**ed up. I also tried the other approach - enter a code - but that just takes me right back to scanning the bar code... FFKS did no one at Microsoft consider testing this **bleep**?
So I thought, well, its microsoft, so uninstall and reinstall - usually works right? Well wrong. I installed the app on my linux, it starts and then tells me I have to install the **bleep**ing app that I have just started, it takes me to a web page that doesnt damned well download never mind give me an installation option.
So now I dont have teams - well done Microsoft, you are excelling, no wonder people are moving to linux... by the way, I worked for you once, I hide that on my CV now, its too shaming.
