### 1/5 — Problem with layout functionality

*2023-10-07, version 2.0*

Hi this looks like it would work very well however n my iPhone 8 it does not work. When I input tge number of pages the keyboard stays up with no way to press the calculate button. Either you need an enter button after the page count or more tge calculate button above the keyboard. Thanks
