Hello, I have the same problem, except I am using Android and Windows. Reinstalling the app and resyncing on the phone did not download all my notes, just some of them, and they are not even sorted in the correct categories.
Update: I tried exporting a JEX file from my other phone, which has all my files, and importing the JEX file on my computer (Windows 11). Here is what many notes look like (all the question marks are supposed to be Chinese characters) On the bright side, at least it looks like all my notes are there, and in the right categories/notebooks:
Downloading the Joplin app on my new Laptop with Windows 11 and syncing with Joplin cloud does not download all my notes, and even those that are downloaded are not categorized in their correct notebooks. This same problem happens when I sync on a newly downloaded Joplin app on my Android phone.
I can export my notes as a JEX file on my Volla OS phone, but if what you mean is that it does not work properly, that would explain the ? symbols.
The other person in the original thread said he fixed it by downloading the test flight version, but that seems to be available only for iOS. Do you know how to solve my problem?
on what system (OS) were the notes originally created ?
from what system(OS) were the same notes originally sync ... to what target ?
does this system still sync without errors (see log) ?
when you export the notes are there any errors ?
before you tried to import the notes into Joplin on win11 -> did you first completely uninstall the Joplin version AND delete the profile folder ?
Reading your two notes I have the feeling you had problems on both devices. In which case I don't think I can help.
The notes were first made on my Windows 10 laptop. I edited them both there and on my Volla OS phone. They were originally synced to a local folder, before I bought a subscription for Joplin Cloud this year.
My Windows 10 laptop is broken and can no longer be used, so I cannot test using it. I can try reinstalling Joplin again after deleting the profile folder. Where is it located?
