Describe the bug

I use NC 27.1.4 on hosted system together with newest NC App & DAV Droid on two Android devices (Phone & Tablet, Android 13 & 11). The Account ist managed via existing NC App Account

News created notes within a notes category cause sync Error Messages and multiple (up to hundrets) copies of this new Note

To Reproduce
Steps to reproduce the behavior:

1. Go to '…'
2. Click on '…'
3. Scroll down to '…'
4. See error

Doing nothing else than creating a new Note.
Reinstalling from Fdroid or Play Store does Not avoid this behavior.

Expected behavior

Not creating unwanted copies of notes

With 'xxx' partially replaced

UPDATE 2023-12-01
Today I deactivated two APPS (Versions & Open In Cryptpad) and deleted the existing copies. --> No effect, the copies are still created after creating new notes

UPDATE 23-12-04
Installing version 4.1.0 RC1 on my Android 11 Tablet shows none sync conflicts/problems so far. Multiple copies were now deleted from server.
Creating new note cause no sync conflict and no multiple copies any more

[Martin-By]

After replacing 4.1.0 with 4.1.0 RC1 on my Android 11 Tablet with success I tried V 4.1.0 on my Android 13 Phone: still sync problems with then following creation of multiple copies.

Installing 4.1.0 RC1 on my Android 13 Phone seems to solve this problems also.

Therefore V 4.1.0 seems to have sync problems whereas RC1 Version seems to be OK.

UPDATE 2023-12-08

Update to Server App 4.9.0, Issue with Android App 4.1.0 does Not solve it.

[Martin-By]

Also after Update of Server to 27.1.5 the Version 4.1.0 created multiple copies after sync Error.
Same for new Notes Server App 4.9.1!

[Martin-By]

Also Beta Version of Playstore with same issue

[Martin-By]

Also with server App 4.9.2 shows same issue

[Martin-By]

With actual updates on Playstore the combination of server (27.1.5) , client (3.27.0) and notes App (4.10). No issue anymore.

UPDATE
The Problem still existiert, so I Had to Fall Back to Version 4.10RC

[lapor-kris]

Same happens here. On Fairphone 5 with Android 13 with Notes from F-droid (latest) and Nextcloud 28.0.4.
My partner gets loads of copies of Notes. But it works great for me on my Fairphone 4 with Android 12 and Notes from F-droid. Odd...

[serversghost]

I have been getting this bug for over 12 months on multiple user accounts with different devices and with all versions of the App & Server updates.

Notes App reports sync error, but still syncs the changes.

@Martin-By & @lapor-kris:

This looks like some sort of web infrastructure matter given the error suggests a character encoding/etc matter with the CSP header:

java.lang.Exception: java.lang.IllegalArgumentException: Unexpected char 0xfffd at 12 in Content-Security-Policy value: default-src ���none��� ���unsafe-inline��� ���unsafe-eval���  ; object-src ���self��� ���unsafe-inline��� ���unsafe-eval��� ; script-src ���self��� ���unsafe-inline��� ���unsafe-eval��� ; img-src ���self���  https://s.w.org https://wordpress.org; style-src ���self��� ���unsafe-inline��� ���unsafe-eval���; base-uri 'self'; form-action 'self' ���unsafe-inline���; frame-src ���self��� ���unsafe-inline��� ���unsafe-eval���

That's what it was for @serversghost apparently in #2093 (comment)
