I cannot sign in to my Google account. I have two factor authentication but neither of my phones receive the CODE, nor does my email account at the address I enter. I suspect the two phone numbers are corrupted (yet again). Online there is a confusing mass of advice, options. troubleshooters but none of it deals with my situation---- it always askes for me to sign in ---- in order to change my sign in details! It would be laughable if it were not so frustrating. Can someone explain how I escape from this endless Catch 22 dilemma? Please don't ask me to sign in, in oder to sign in. My account must be active, otherwise I could not have got here.
