Can't save on iPad

Hi guys. So I bought Siralim 2 and downloaded to my iPhone 7 and iPad Air 2. I have been playing on both units, save in the cloud and can import from other unit no problem. I usually overwrite the other existing save because current one is newer. Now I was playing on iPad and went to save and overwrite the old one but it just says please wait, acquiring a file handle. And it just sits here forever and does nothing. I get out of the game by swiping running programs off like usual and start it back up and it does same thing, not saving. Any suggestions? Thanks
