Worst app for robot vac. Had my vacuum for about 2mths and have yet to be able to make an account bc it keeps saying "incorrect token" when I get to the set password. I have tried to resend the code but every time it says incorrect. It worked without the account set up before but now that I had to switch wifi, I can't set it with the new wifi bc the account can't be completed due to "incorrect token" still. Very frustrating.
