Permutation and Combination

This was a great little app, but on the last update, the scroll inputs (from and choose input numbers) are now blank. The results still show but I have to blindly attempt to change the inputs until the output looks correct. It was 5 stars before before that (and it may work for you... but if you update the iOS, Apple purposely kills your battery life to get you to buy a newer phone).

Up until i had to update my software this was my go to program for determining P&C but now the scroll bars are invisible AND the final results are invisible as well. Please fix!

Currently not working for iPhone X newest OS
