App is true to the original, latest update caused display issues – HP 15C Calculator Review

I don’t know whether it’s related to an iOS update, the latest (2.3.2) app update, or a setting on my phone (iPhone 11, 13.3.1), but the font size has been reduced on both the landscape and portrait views and the display numerals’ location has been moved out of the display area on the portrait view. Please update the app or advise potential causes and solutions to this problem. Thank you!
