8.2.1. has the dame problem with removal of settings / library, also crashes still on latest tvOS when manual restore of settings is clicked
When choosing to manually restore a cloud backup Infuse will remove the current library data and close the app. The next time the app is opened this library data will be restored from the latest cloud backup.
Also, Infuse 8.2+ will support multiple profiles on Apple TV so each user can have their own separate library. More info on using this can be found in this guide.
