Making nextcloud sync work on the phone

[sfb]

I figured that since Mobian is just running Debian, I could install the Nextbutt desktop client. However, the app doesn't scale even when I run scale-to-fit, and when I finally got it set up, it didn't apppear to do anything. Also, whenever the client loses focus, the whole app appears to shut down.

Is there a way to get nextbutt synchronization working with Mobian/Phosh?

Have you tried to configure your nextcloud access in settings -> online accounts?

after this you can sync calendars and contacts but also access your files via the file browser.
Works like a charm for me.
