RMStore "Cannot connect to iTunes Store"

Question

I've integrated RMStore in my project using cocoapod. The integration was successful and I've followed RMStore demo and integrated in app purchase logic with receipt validation.

In receipt validation, instead of build number, version number is assigned and when I tested with AdHoc profile,

I received "Purchase failed" error.

I rectified this issue and replaced version with Build number and took another build and while testing this build throws "Couldn't connect to Store" Error.

As mentioned in other stackoverflow links, I tried logging out of my official id and tried with test id but error still there.

FYI, though it doesn't work in simulator, While testing, I accidently logged in using official id for testing... will that create any issues while testing in real device?
