Hi
This is perhaps related to an earlier post (Renaming tag on Android does not sync to desktop).
I edited tags on my Android phone, making some of them context/area tags (@ prefix). This change does not propagate to my desktop (Linux).
Also, if I now add an @TAG to an item on the phone, it will appear as TAG on the same item on the desktop.
The process works if I create context tags on the desktop: these propagate correctly to the phone.
