To many bugs

I had high hopes for this app. Since it cost $20 I thought it would be pretty good. But I can't change the "Proposed installation conditions". When I do the app crashes and boots me out back to the home screen. So I thought I would tell them about the issue in the in-app feed back, but that won't work either!
Good try gen cable, fix the bugs and then the app might be worth the $20. But untill then I am pretty disappointed!

Developer Response ,

Sorry about the issues you previously had. The app has had a significant update since 2013. I suggest you give it another try.
