I have the same experience!

In my case, my personal and professional Microsoft addresses are the same (same email, different accounts) which means that in many cases I end up in impossible situations when the login screen doesn’t correctly guess if I want to sign in personal or with my “work” account. I also do client work for organisations where I need to sign into their O365 and honestly the only way to manage all that is to keep a dedicated browser “per account”.

Teams is a different story, I avoid account switching because exactly like you describe, sometimes I need to uninstall it in order to sign out.
