### 1/5 — The pictures do NOT show as advertised

*2019-03-31*

This app has a beautiful layout  when viewing the images. However, once downloaded there is only a list of text boxes that pop up with very limited information .The unit circle, trigonometric identities , half angles, etc nothing is there.There must be an update or I need my money back. VERY DISAPPOINTING.

**Developer response:** Move your iPad around until it says”portal detected”, then tap the screen to open the portal. Once you are inside, walk around to visit the rooms. Tap to read and learn more about each concept. You need to give the app access to your iPad's camera in order for it to work correctly.  If you are still having trouble please contact us at sales@venturaes.com.
