DraStic

I purchased DraStic DS many months ago and recently installed it on my galaxy s6. When I open the app everything seems to work fine except for the screen being alot smaller than the screen of my phone. I've heard that this is an issue with bootleg versions of the app but i assure you I've paid for mine. I have screenshots of what's going on and screenshots proving I paid for it. I could probably dig up a reciept if I need to. Please help.

Are you running the latest version (2.4.0.1a)?
If not, please try updating first.

There can be different reasons for small screens, including some corruption in the screen layouts.
If you still get it after updating, try deleting all files in /sdcard/DraStic/config, then restart the app.
