I’m having the same problem too. It’s not anywhere on my mail (Yahoo). I was able to log on my account by linking my boyfriend’s cellphone to my account (his network was already saved). For some reason the authenticator app won’t work on MY phone.
I sent in a ticket and replies from the support team seem to be going through fine (even though support wasn’t much help). However, I’m also failing to receive any “reset your password” emails. So in the end it seems like nothing works…
This is only a temporary fix for me, since my IP changes every time I reset my router (for X or Y reason), so I keep on having to authenticate myself over and over again. Please help
