I have the same problem.
Having initially installed this on my mobile phone i think this was my initial device however i logged i forgot my password and there is no password reset button despite online guides saying their was.
since then i have logged in on my pc, i can access the account, delete device, and reconnect them, but i still get no verification pop up so am unable to sync anything.
hope you can help please. ideally asap because i need to resolve this soon or purchase another product before i go on holiday.
thanks
