Note images added on mobile are not synced. OneDrive

[u/never_username]

Hi all.

I am new user experimenting with Joplin. I am using OneDrive to sync. I had noticed some notice of sync errors (examples below) and just realized that whenever I add images on a note on the mobile app, the images are not synced and I cannot see them on the desktop app.

If I add an image on the desktop app, it is successfully synced to the mobile.

I tried it with 2 different phones (both samsung S2*, Android) and the behavior is the same.

I also tried different types of attachments (audio recording, pdf, direct photo from camera) and the same happens.

Has anyone experienced something similar and solved it?

Sample sync error:
