iCloud saving doesnt work

I purchased this game with the expectation of being able to transfer my game save files through the iCloud between my iPad and iPhone. However the saved file that I upload to the cloud is not being transferred between devices. The actual Game Center data and achievements is transferred between devices, but not the save file I upload to the cloud. I contacted the dev and was told to contact Apple support and Apple support was not able to help. Leaving this review at 2 stars until the issue is fixed.
