"Token-based authentication not supported" when connecting to Nextcloud subsonic server in 2.0.0 alpha 3

[thecivilizedgamer]

Describe the bug
I have a subsonic server hosted on Nextcloud (using the Music app, https://github.com/owncloud/music/releases/tag/v1.8.4). On version 1.3.0 of Subtracks, I can connect to my server with no problems, if I enable plain-text authentication. However, on the 2.0.0 releases, I'm unable to connect. For alphas 1 and 2, clicking "Save" on the add source page doesn't do anything. In alpha 3, I get the error "Subsonic Exception [41]: Token-based authentication not supported," regardless of if I have the "Force plaintext password" slider enabled. Perhaps the slider value isn't getting applied correctly?

To Reproduce
Steps to reproduce the behavior:

1. In 2.0.0 alpha 3, go to Add Source
2. Enter credentials/connection info for Nextcloud Music subsonic server
3. Enable "Force plaintext password" slider
4. Click Save
5. Error message "Subsonic Exception [41]: Token-based authentication not supported" is displayed in a red box

Expected behavior
A connection can be made to the server.

Device

• Model: Pixel 6a
• OS: Android 13
• Subtracks version: 2.0.0 alpha 3

Server

• Software: Nextcloud Music app
• Version: 1.8.4 (https://github.com/owncloud/music/releases/tag/v1.8.4)

Additional context
I know this may be difficult to reproduce depending on what servers you have available for testing. If necessary, I can provide a temporary app password for my self-hosted server.

I am having the same issue using LMS backend.

I'm having more or less the same issue here, running airsonic-advanced as my backend. But my error message is a bit more different, I got "SubsonicException[41]: Wrong username or password, but try authentication via non-hashed password.". Toggling "Force plaintext password" also did not help.

The password & username is correct, signing in with the stable release works. I also tried logging using the demo subsonic server and it works. Maybe because of slight differences in API implementations between subsonic and airsonic-advanced?
