Please add pinch to zoom in the integrated PDF Viewer. Having to use the controls is not a good user experience on a mobile device, plus it typically crashes the app if you hit the + symbol too many times quickly.
Updating status and adding @FilipK
A very important function that must be added. +- controls are a thing of past
I agree, please add the pinch to zoom.
Pinch to zoom seems to exist now on iOS. ...But it crashes the app and there's no way to disable it.
The pinch to zoom is still crashing on some iOS devices, it doesn't matter if zooming in or out, the app just restarts itself.
