I am trying to add an existing gmail account to my laptop. When I type in my gmail account on my laptop I get an error message "couldn't find the google account". The account is valid because it is on my cel phone. Went to account settings and got this "couldn't access account. You might need to update your password or account permission to sync to this device." Password is good and sync is on. Went to recovery and it asked for the gmail account with the same result, couldn't find. Can you help, please?
