I can confirm that what you are stating is incorrect. The ability to save PGN files to your computer has not been removed. What task were you able to complete before that you are unable to complete now?
Are you attempting to save copies of your game onto a program on your IPad? I'm looking at the instructions and it's looking like you can copy and paste the game into your program of choice and save the pgn file there or copy it to a text editor or a program that you can save the file with a .pgn extension (A PGN file is esentially a text file).
