I've had trouble with all the services (MSFT and others) sending texts. I blame Verizon more than the big tech folks though, as their SMS is remarkably unreliable. That said, my first pass through MSFT 2FA hell left me with the indelible impression that they really didn't understand 2FA. I only reluctantly use their products, and have been hit with various "Temporary problem" when attempting to login. Its worse with SSO, in case you are not sure. More to the point, every scenario where I'm forced to use a MSFT product, another product exists which does a far better job, with far fewer bugs, far better performance, and far better UX/UI. Its as if MSFT hates users.
