### 1/5 — App crashes when opening

*2017-04-24*

The moment you open the app there's a pop-up with a code error and the app closes. How did this make its way into the app store?

**Developer response:** Hey, thanks for your review. This error pop-up appeared when the app was opend on an iPad used in landscape mode. We fixed this error, so the app starts without errors all the time. We would be very happy if you could review the app for the CASIO graphing calculator again :)

### 4/5 — Cascorrection

*2017-11-05*

There was an issue with CAS. After getting in contact with the help desk, the issue was solved ASAP. The app has been a great help in learning about the Casio 9860II graphic. The manual is helpful, and the help desk is responsive.

### 5/5 — Geht nicht

*2017-03-03*

Runtergeladen, 4,99€ bezahlt, versucht zu öffnen. Nach kurzem Überlegen erscheint die Fehlermeldung "Error #404 - uncaught error, null is not an object ....", die man nicht über "ok" wegklicken, sondern nur nach oben oder unten schieben kann, bis die App abstürzt.

**Developer response:** Nutzen Sie ein iPad? Uns ist bekannt, dass dieser Fehler im Landscape Mode auftreten kann. Versuchen Sie die App zu starten, indem Sie Ihr iPad so halten, dass der Home Button unten ist. Eigentlich sollte dieses jedoch mit der App-Version 2.2.0 behoben sein.
Wir würden uns über Feedback freuen!
