PDF Annotations/Features disappearing

Issue

Annotation options disappear while navigating in PDF brochures/publications. 

Cause

The options disappears due to device orientation changes from portrait to landscape 

Solution

Hold the device more vertically and try opening the annotation features/making annotations again. This time it should work. In the worst case you can temporarily activate orientation lock on your device, but we don't recommend this, since in other situations it may cause the app to crash.
