Six days ago Gmail stopped recognizing my Thunderbird accounts during the day. Three of the accounts were re-connected. The fourth account is still a problem. Gmail says that it does not recognize my computer and is looking to verify the account. The email backup account was asked to verify that the activity was me -- I did that. Now, Gmail wants to send a verification code to my old phone #. At one point in this process I was able to change the phone # to the current phone number. I got a confirmation of that change, but Gmail continues to want to send the verification code to the old number. There is a "other ways to verify" link on the Gmail page, but the ONLY option is my OLD phone #. Any suggestions ?? Thanks
