Love product but needs work – Mind Benders® Level 5 Review

I love all the products from The Critical Thinking Co. and was thrilled to see them available for iOS. However, the app does not work on my iPhone 7. I can get the app to work on my iPad. I would also like to see a “clear all answers” or “clear the board” option for when the puzzle needs to be restarted because of something done incorrectly.
