Summary
Modification/update times aren't being updated by the beta image editor on iOS and Android.
This causes changes to drawings not to be synced.
It should be fixed by this (merged) pull request. A new beta release should be available soon. Until one is, be aware that drawings may not sync properly.
Preventing data loss on sync
The next time a resource is edited in a way that does update the modification timestamp, that copy of the resource may overwrite other copies without producing conflicts. This is because its timestamp will be newer than all other versions of that drawing, which all have their timestamp set to their creation date.
To prevent edited copies from being lost, you can
- Make a JEX backup (Configuration > Scroll down to "Export" > Export all notes as JEX). This saves the edited — but not correctly synced — drawings to the JEX export file (tested on iOS).
- Alternatively, long-press on a drawing and click "share" to save the modified copies of the drawing externally.
- After the pull request is merged, opening a drawing in the image editor and clicking Save should update the drawing's last modified timestamp. (Make sure that the version you first click "Save" on is the version you want to keep! Incorrect last modified times may prevent conflicting changes from being moved to "Conflicts".)
Original post
Overview
While testing the js-draw-based beta editor on iOS, I encountered a very strange sync issue that I haven't since been able to reproduce (except for with a single resource).
Interestingly, there seem to now be two files on OneDrive with the resource's UUID, one in the .resources folder and one with a .md extension. Edit: This is expected. See comment below.
It would be helpful to know if this is happening for anyone else (and if there's a consistent way to reproduce this for new attachments).
What I did
I attached a new drawing by clicking the "Draw picture" button under the note actions menu. I drew something, then clicked save, then close (if I remember correctly).
I then synced my (iOS) device to OneDrive. After that finished, I synced a desktop client to OneDrive. The drawing renders to this:
I then tried editing the drawing on the iOS device and re-syncing. Nothing changed.
Other drawings can be added on the iOS device. After syncing, the other new drawings show up, as expected, on the desktop client.
The markdown for the drawing looks like this:
If I remove the exclamation mark and click on the link, a dialog shows the error
