This is what frustrates the heck out of me when platforms decide to redo their entire user experience, just because they feel the need to "change something".

Thereby forcing all of their users to learn the new UI immediately, not even with due warning.

One or two platforms doing is in a week or so is a pain. But when lots of platforms do this in a short period of it, it can be "throw hands up in the air and do something else". :(
