First off, thanks for the contribution.
So I followed the instructions several times and this is what is happening on iPad 4 running 7.1.2 using xCon 40 beta 1, iAPCrazy from BYA repository and the .deb file installed via iFile.
I open up Famousgram v2.2.1 and I try to purchase the "2,000 followers for $99.99" item and hit cancel on the Apple ID password prompt and immediately tells me "Order Failed Please try it again".
I close the app via multitask and reopen and the problem replicates.
So I was able to download a copy of the v2.2.0 IPA of Famousgram, installed it and still the same error is presenting.
May someone please tell me what I have to do in order to get this to work? Or what to wait or expect? Many thanks.
