The most uncomfortable part is their log in. The amount of re-directs and glitches there are insane. Its hard to believe that it works as intended.
As an example, for some reason I could not download the BAA because trying to download it lead to a login loop on their trust website, while I was still able to see the Azure console ok in the same browser.
When I signed out of my Azure account to try if a fresh login helped, it did not trigger my 2FA at the next login. In my mind, if I actively logged out from a browser window, I withdraw my trust in that device. So not being triggered for 2FA is a massive red flag.
(no I still could not download the BAA, nor file a ticket for it, but somehow a colleague could download it ok.)
On every first try, I cannot log in into Azure Portal. I chlick "try again", it works. And it's like that for months, if not years.
IMHO it says a lot of your culture if every first interaction of your customers with your product end with an error - and you simply don't care to fix it.
It is probably my "fault" by using Safari (no extensions) and not the all-praised(tm) Edge.
I couldn't add a billing profile to my MPN account the other day - endless loading without any indicator of success. It did work in Chrome though, except the "save" action which resulted in endless loading too, but still saved everything as expected.
