Something that I was struggling with recently is the Edit button on the iOS version of Google Authenticator, that doesn’t do anything. I wanted to rename the obscure AWS description, but couldn’t figure out how.
After visiting my favourite search engine, I discovered that I’m not alone.
The workaround (thank goodness there is one) is to go into Legal Information first, and then the Edit button works (thanks to Ilkka Mattila for pointing this out).
