It seems adding tags does not trigger a sync of the note, at least for me.
- Platform: Ubuntu
- Platform version: 16.04
- App Version: 4.1.0
- Add some notes.
- Sync them and check on, e.g., Android.
- Now add some tags and sync manually.
- Check again on the mobile phone.
-> Tags still missing.
Btw: Is there a way to force syncing all notes again?
