What steps should I take if my projects disappear? (iOS)

If you have deleted the app and reinstalled it, all data in LumaFusion, including projects, will be deleted. The only way to recover in this case is to restore from a backup of your iOS device. This article from Apple describes how to restore a backup.

If you haven't deleted the app, we have found that sometimes this can happen if your iOS device storage is nearly full. Your projects aren't really gone in this case. The following steps will usually resolve the problem:

• Free up as much storage as possible. 
• Restart your iOS device.
• Restart LumaFusion
• Import a Project Backup using the Project Manager
