This feels a bit like user blaming. Imagine someone getting to the office and getting annoyed at you because they changed their name, didn’t tell you, and you used the wrong name. You could have looked them up in the corporate directory, but you don’t know what their new name is and their previous name is no longer listed.
Communication was poor, mobile OS’s should probably account for this (if for nothing else to prevent major functionality pivots / spam ware) etc. parents displeasure and me losing all my mfa tokes feels like a total rug pull by google, a pattern they are known for (sure, fool me twice, shame on me - but I never expected their mfa Token app to delete all my tokens).
Fun fact: the name of the app did not include "authenticator" before the rename. Because guess what, my Android phone is not in English. So the name was the localized version of "Google Authenticator" (I think it was Google認証). Now it's "Authenticator". No "Google", and not localized, and, obviously, not at the same place while sorted with everything else. And not the same icon.
