Corrupt sync metadata / revision IDs causing decryption errors on iOS – Need help to identify and de

Operating system

iOS

Joplin version

13.5.3

Sync target

Joplin Cloud

What issue do you have?

Dear Joplin Team,
I am at my wit’s end. I migrated from Evernote to Joplin and have been experiencing constant sync issues ever since.
What I did:

Imported all notes from Evernote to Joplin on my MacBook and connected it to Joplin Cloud. Initially, encryption was enabled.
Installed Joplin on my iPhone and iPad Mini, connected both to the same Cloud account, and synced.

From day one, I received errors on iOS: "Some elements cannot be decrypted" or "Invalid property format".

Troubleshooting steps already taken:

Deleted and reinstalled the Joplin app on all devices multiple times.
Disabled the "prevent deletion if remote is empty" setting on iOS to force a clean sync.
Deleted all .config/joplin-desktop/ files on MacBook.
Disabled encryption entirely.
Used Victor plugin to completely wipe Joplin Cloud (reduced to 30 KB).
Re-imported all notes (6 GB) from scratch on MacBook and synced to Cloud.
Disabled the 90-day note history retention on all three devices before syncing.
Spent days re-syncing with the screen on, causing multiple app crashes.

Current situation:

No errors on MacBook – everything works fine there.
Persistent errors on iPhone and iPad Mini with the following revision IDs from the log file (log.txt):

2026-05-03 19:55:34: Synchronizer: Sync: createLocal: remote exists but local does not: (Remote 67c7dca0648547478dccb0a628ea4a7e.md)

What I need:

How can I identify and delete the notes associated with these revision IDs?

I only have the IDs from the error messages.
I searched the log.txt file but only found the above lines.

Why do these errors persist even after a complete reset of apps, local data, and Cloud?

I would be extremely grateful for any help to finally resolve this. Thank you in advance!

Due to forum restrictions for new users, I can only attach one screenshot. I can provide the remaining four screenshots of the error messages upon request.

See How to delete corrupt server items which cannot be decrypted

This is fine if you have a small number of items which say they cannot be decrypted. But if there is a lot, then you have a bigger problem
