I found there are problems in using the Ho prime apps in cas mode and most of cas functions, simply key in proot (2*x^2+3*x-2) then press enter, it goes dark and jump out of the apps. Could you tell me how to solve the problems. My IOS is 12.3. Is anyone has the same problems?
The app doesn't fit on iPad Pro 12.9"
I found there are some spaces on the left and right side in my iPad Pro 12.9" after I started up the HP Prime Calculator app.
