What issue do you have?

Joplin desktop app not syncing with dropbox after reinstalling Windows 11.

I have it syncing on my Android phone and it works fine, but after reinstalling Windows 11 it refuses to sync. It will authenticate, I hit synchronise, but it never adds any more notes. It still just shows the welcome notes for me.

I tried importing the notes into Windows 11 manually, but it never syncs them again when I update them on my Android.

I also tried deleting the profile directory, but it doesn’t find the notes when it synchronises with dropbox.

I also tried "Delete local data and re-download from sync target", but it did nothing.
