• If you have the Files app open on your device, force quit it
• Tap and hold the Infinity Lists icon, and choose "Files"
• This will take you to the app directory: On My iPhone(or iPad)/Lists
• You should see a ListMaster.realm file there, save that to a folder of your choosing in iCloud Drive
  (If there is only a ListMaster.realm.bkup file, save that and rename it ListMaster.realm in iCloud Drive)
• On your computer, find that ListMaster.realm file in iCloud Drive and open it with Realm Studio
• Realm Studio will ask you if you'd like to convert it. Say yes.
• Use the Files app to place that converted ListMaster.realm file back in: On My iPhone(or iPad)/Lists
• Now, open Infinity Lists
