HP12C Platinum app not working with iPhone or iPad now – HP 12C Platinum Calculator Review

After updating my iPhone and iPad to iOS 14 the app does not work for basic payment calculations and the app closes randomly. I’ve owned both the 12C and the 12C Platinum physical calculators in the past and I am now forced to use someone else’s app. HP please update your app!
