To be fair, the win version is what I found on my desktop. The phone version is apparently 10.82.0; according to Google Play, this is the latest version, released on 3/26/24. Does that mean I need to wait until the Google Play store has the 10.83 version? It still seems odd that what looks to be a small update would mean that I can no longer use my regular email/password to log in, but perhaps that is the case.
