That's total "normal" for Microsoft at least from 2018, the year I started working with some of their products (Power BI mostly). They adopted a development model that is early release, fast iteration, and users as testers. No wonder everything feels experimental until much later.
Back then I just couldn't use Power BI. But fast forward a few years, I think it got a lot better since maybe 2020. You just have to stick with it for a few years.
Man, what a horrendous pile of crap Teams was back then. The Slack teams were griping that they should just buy Slack, but Teams was the "enterprise solution." The problems were amplified during remote COVID work. Teams is fine now, but how many corporations went through years of frustration just because some IT decision maker said "Teams. Because it's enterprise."
The UI is an overengineered mess and I'd rather use literally anything else, but to say it's still unusable is disingenuous.
and indeed your entire workplace,
for as little as a steak dinner.
So, you have to be a paying tester? Incredible that MS can keep enough businesses as hostage to be able to operate like that.
People who take Azure up without previous MS product experience...not sure about those.
For everyone else, it's like you said. "Eh, we are already knee deep in the Microsoft stack, why would we pick anything else?"
