Great potential, poor syncing

Still same issue after major update.
If the developer could get background sync to work properly across devices, this would be a terrific 5 star app. Without solid sync, however, it is often annoying -- as changes on one device are not reliably updated on others. I am using the Dropbox sync option, which the develop recommends!
