There are two of us on the account, me the account owner and my spouse an account manager. Since changing my plan and upgrading to a new device, when I log in using a browser on my Windows laptop, it wants me to use 2FA with my spouse's phone number, not my own. When logging in from my new device, I have no problems.
I saw a post suggesting that might happen for a week? I was chatting with a rep today who wanted to "unregister" both our accounts, whatever that is. I work in tech so I'm not a dummy, but I think your rep was not going in the right direction. Can someone explain how to fix this?
