I added a third Gmail account last night.
I am unable to log into it from another computer. If I go to gmail.com, it takes me to https://mail.google.com/mail/u/0/#inbox (automatically logs me into one of my other accounts).
If I then click "Add Account" on the upper-right button or icon (with my image or avatar), it takes me to a page where I can "Choose an account," but it only has the two previous accounts listed, not the one I added last night (which is open and available on the original computer).
If I choose "Add an Account" again, there, it prompts me to sign in to to add another account, with the email address of the account currently open and a "Next" button. But nothing leads me to where I can select my new account.
I know it's possible to have multiple Gmail accounts simultaneously open, because I always have different ones open at work, and I now have the three at home simultaneously open.
So how can I find and open my third and newest account from a "foreign" machine (not the one on which the account was created)?
