If instructed by Ingen to reset the device to try and re-sync information, the following steps are how that is done:

2) Clear the app data
On the device, go to "Settings" then tap on "Apps". Find OASIS in the list and tap on it. There will be a button that says "Clear Data". Tap on that to delete all synced information.
3) Restart the sync
Follow the steps in the following help docs to restart the sync process.
