What happend after clearing the storage and reimport your account as described in the FAQ?

[benginoe]

A cleanup of cache doesn't resolve the issue. But downgrading to this version (https://github.com/nextcloud/notes-android/releases/download/4.4.2/nextcloud-notes-40040290.apk) resolves the issue.

Nextcloud 32.0.0

[davidvanwijk]

So, then sync works on nextcloud 32.0.0? Thanks, David

[benginoe]

Yes with the older app version it works flawless with Nextcloud 32 server.

This from https://github.com/nextcloud/notes-android/issues/2826#issuecomment-3453542215 also sounds interesting / relevant:

Update: I sideloaded the 4.5.1 release, and it fixed all the problems, including sync of editing existing notes, and creating new ones from the mobile app, as described in the linked issue https://github.com/nextcloud/notes-android/issues/2850 .

To clarify, this issue was reported as happening in 4.4.2, but other commenters have stated downgrading to 4.4.2 as a fix. Like them, I had these problems after upgrading from 4.4.2 to 4.5.0, using F-Droid in my case. I had to uninstall 4.5.0 in order to install 4.5.1, but then I simply selected the Nextcloud account to use, acknowledged the prompt to allow use of that account, and all my notes populated. Then I was able to edit and sync notes normally again. I also tested creating a new note, and it worked correctly.
