Tried everything. Also, I changed phone (just device) 20 days ago, but installed mcsft authenticator and logged in, but it not works properly, no pop-up notification, when asked for second step verification trough mscft authenticator. Don't know what to do. pls help. I can send you my last bill number for example, it's:
