Hi - I have a fire 10. Am trying to setup communications on the Alexa App, so I can get to my dad's new Echo Plus/Dot for drop in (as he is just out of hospital). I entered my home phone number (that accepts SMS msgs) as the one to verify, but no messages come through and I now can't change the phone number on the App (to be my mobile one - as this is hared with work, I didn't want to use it from the start).
Thanks - So I have an Amazon account a Kindle and a Fire all linked to the same account (in theory). The Amazon account has my mobile no. I have tried Sync Device on the Fire, made no difference. How do I sync?
