Hi @Eric_Olson,
On iOS, deleting Roon ARC will prompt the option to fully uninstall and delete the app’s data from the phone. On Android, just uninstall and reinstall the app, and delete the app’s data in Settings - Storage, depending on your version of Android.
If you have a significant volume of local content downloaded to the phone, you’ll need to redownload these tracks to your mobile device in ARC when ARC resyncs to the Core again after reinstalling. This is similar to hitting “Reset Roon ARC” within the app.
All of the above steps differ from a Roon database refresh, which would require restoring a Backup to not wipe out your library and customization. There’s no need to refresh your database in this case.
If reinstalling ARC isn’t successful, you can reboot the machine hosting your Roon Core. Since the server outage manifests in the short term as an authentication failure - and subsequent hang - restarting can refresh underlying conditions and sometimes bypass the issue.
