Zoom has been disabled in the Android app?

The Android app just updated a day or so ago and along with some UX changes, pinch-to-zoom has been removed from exercises.

Why?

It was very useful in certain situations like when dealing with graphs, especially on smaller screens. I can foresee as lot a students getting frustrated because they misread part of a graph that was a few millimetres across on their screens.

This must have been some kind of oversight, right?

Please fix this issue on an otherwise good app and great resource.
