    I can only access this app by opening it via the App Store. I deleted the free version yet still this app’s icon did not replace it. What could be going on here?

  • Changed all of a sudden

    Been using the pro for long time w/o the advertisements, all of a sudden , just over nite I was trying to use this morning the numbers on the keypad are very large, cannot see the calculations screen. Rebooted iPad but had no effect, deleted from desk top, reloaded it now I have very large numbers with framing advertising. Can not make the calculator fit the screen like it was yesterday. My IOS 13.2.3 is what I use , I cannot provide more specific info, other than the above description. Had used it the nite before when I went to use the calculator it was very large with only a few numbers visible on my screen even in landscape, again I tried the steps above before I deleted it and reloaded it. Had to pay for the pro again to get rid of the advertisements.
