New version still needs fixing

I've been using this app for quite some time and really enjoy it. The new update brought some good and bad, bad being I had to buy the unlocked version, again, to fully utilize the app. The last fix solved the pink background issue. However a new bug that shows up is the distortion of screenshot pictures where parts of the rifle are missing, and the fact that logos and engravings are very pixelated in the app now. I'm sure these will be fixed and once they do I'll change my rating.

Can't get full version.

It says that if you bought the other gun platforms (ar-308,r700) and/or the full hd version previously then you can restore purchases to unlock the new full version, but I've tried to do it a few times and I still can't get the full version.

Was great

This app was the most used thing on my iPad until the latest update. It won't let me restore my purchase to the full version that I previously bought. And the background is solid pink... please fix
