I recently got a new iPhone and downloaded Fallout Shelter but my Vault from my old iPhone isn't appearing in the "My Vaults" list. On my old phone the "Cloud" box is checked next to the vault so I assume that means it is saved to the cloud. My iCloud Drive is activated on each phone with Fallout Shelter also turned on in the settings. Any suggestions? I need to trade in my old phone soon so time is of the essence.

Thanks!
