Currently, this is not possible. What you can do is 'restore' your notes/point groups on your phone app (if you have to re-install the app on a new phone for example). Simply press 'restore' in the 'My MoA' menu to do this.
When the new version of the Online Edition is released (hopefully by the end of March 2018), you will be able to see your phone app notes/point gorups in your Online Edition account. But Online Edition notes will not show up on your phone app.
In the future, we hope to enable true syncing between accounts, but we don't have a release date for this at the moment.
