Sad This App No Longer Works – HP 12C Financial Calculator Review

I’ve used this app for years, and never had any problems. Recently I noticed that it would not convert to a traditional HP 12 C on the horizontal. I deleted the app and reinstalled but that doesn’t solve the problem. At this point it’s only a calculator without the full features of an HP 12 C.
