i tried all that... didn't work. looks like the only way to use in my phone is by uninstalling and reinstalling every time there's an update. 😂

There's a cheaper version of your workaround, and the code says why it works.
The file that goes stale is `server_type_models.json`, cached in the app's own directory. The app only deletes it in `invalidateApplicationTypes()`, and the places that call that are the session-reset paths — login failure, logout, an offline-DB migration. Nothing deletes it just because you updated the app. So after an update the stale copy stays, the app has to refetch, and if that refetch doesn't go through you get the "offline login unavailable" wall. Reinstalling works because it wipes app data, which takes that file with it.
So instead of uninstall + reinstall, try: **log out and log back in**. Same effect on that cached file, without re-downloading the app.
Fair warning so it isn't a surprise: logging out clears the local offline copy of your mail, so it re-syncs from the server afterwards — same cost you already pay when you reinstall, just faster.
If it happens again on the next update, that's worth sending to them as a bug report, quoting the class rather than the symptom: "cached server_type_models.json is not invalidated on app update, so a failed refetch blocks login until app data is cleared". That's a one-line fix on their side and they can't act on "it broke again".
I can't test any of this on your phone — it's read from their source, not reproduced.
