Hello,

With respect to the Android exception caused by this issue I have fixed the
bug:
https://github.com/GEANT/CAT-Android/commit/088a94b6184bcff0fe3ae354b1e76c44
08ffd8ea

I have pushed a fix for this issue to GitHub, and uploaded the new app to
production in Play.

It will start updating on end user devices within the next 24 hours.

Gareth Ayres.
