Continous Loop Sign-In Problem

Hello, after years of no Yahoo e-mail problems, suddenly I can;t sign-in. I click in my phone number, a code is sent, I copy it carefully, type it in the correct spaces and that takes me back to square one. I tried clicking on an alternate e-mail address, with the same result. Is there no way to fix it? It's only a problem on my Samsung Galaxy Note S9+ with Android 10. On my Dell laptop, Yahoo e-mail works fine. Can this be fixed?
