Crashes every time I select a document in the app for an iPad mini using iOS 9.

Please please help fix this, I have an online textbook I have not been able to access.

Edit: now crashes when I select a textbook on the iPhone app (iOS 10) and does not allow me to send crash reports on either device.

Clearly developers don’t care about this app

Contacting them is useless. They just tell you to contact the content provider without understanding the issue is on their side

Crashes incessantly!

Two stars for being able to open locklizard documents. If you actually want to read more than one or two pages, forget it because this app crashes constantly! If you swipe to the next page, it crashes. If you pinch to zoom, it crashes. If you rotate the device sideways to landscape view, it crashes!

Please fix this app.
