Notes getting lost

[marxjohnson]

I'm having an issue with notes getting lost.
I had a note that I had updated through the web interface. I then opened it on my phone in the Notes app, but it couldn't sync the updates. When I looked at it again through the web interface, it had lost the updates!
I just tried to reproduce the problem by creating a new note. I was able to update it and sync the updates to the Android app, although there were errors shown in the log. However, I then tried to open it again in the Android app, and it had been deleted, no trace of it through the web interface either.

Here is the tail of the error log from when I created the new note. It was called "Test note", I'm not sure if the lines before that are related, but I thought I'd include them in case they shed some light.

I now can't use the notes app for fear of data loss, so hopefully this problem can be fixed.

I just remembered that I had versioning turned on, so I was able to restore a previous version of the file that originally experienced data loss.
