Turn off syncing on cellular data when traveling internationally
Traveling overseas and uploading data on a cellular mobile connection can be costly. To avoid charges, turn on "Sync on Wi-Fi only" within your settings. This will stop the app from syncing over a cellular or mobile network.
Please remember that once you do this you will only be able to sync notes when connected to Wi-Fi. Remember to turn this setting off again when you are back in your home region.
