Brand new self-hosting server asks me for 2FA when trying to log in with existing account; rejects existing account's 2FA codes

I have an existing StandardNotes paid account, that I've been using with the SN's own server. I have 2FA set up on that account for logging in.

I'm testing the StandardNotes self-hosted server, and I've set it up on Docker on a server on my network, using the instructions here.

It works fine, and I can connect to it with a "virgin" SN free account I set up for initial testing purposes, from my desktop app, on a laptop on the same network. (Different email address from my existing SN paid account.)

I then tried setting up a separate Workspace in the desktop app, to sign into my self-hosted server using my paid account credentials. (If I'm ultimately going to move to my self-hosted server, I still want to be able to access my paid account functionality when using it).

However, on attempting to log in to my self-hosted server, Standard Notes tells me my 2FA credentials are incorrect. I'm not sure how the self-hosted server "knows" that it should request my 2FA code, since it's literally brand new and I've never logged into it with 2FA activated.

So I assume 2FA is requested as part of the app's log-in process and tried the following:

• Logged into my existing paid account via the web app and disabled 2FA.
• Confirmed I could log in to web app and desktop app hosted workspace with just username and password of my existing paid account

Then:

• Tried logging into existing paid account on self-hosted workspace via desktop app - 2FA requested (despite my having disabled it for the account), and generated code rejected as incorrect.
• Without re-enabling 2FA:
• Completely uninstalled desktop app from the machine I'm using on, re-installed, tried logging into self-hosted server with existing account - 2FA requested, code rejected as incorrect
• Installed desktop app on another machine, on which the desktop app has never been previously installed, and tried logging into self-hosted server with existing account - 2FA requested, code rejected as incorrect

So I'm not clear at this point what's going on. I can log into the SN-hosted server with my paid account just fine, with 2FA either enabled or disabled; but the app won't log in my paid account into my self-hosted server because it asks me for a TOTP regardless of whether 2FA is activated for the account or not; and tells me that my 2FA credentials are incorrect whenever it does.
