ios - "Cannot connect to iTunes Store" in-app purchases

Question

I am having problems testing my in-app purchases. I get back valid product identifiers, but upon purchase I receive the dreaded "Cannot connect to iTunes Store". Interesting thing is that restore purchases seems to work - iTunes login pops up.

I have: - Checked that my in-app purchases are cleared for sale - Checked, rechecked my source code to be in sync with Apple's documentation - Added appropiate test users - app id does not contain wildcard - in-app purchases are linked to the app (app itself is in developer rejected state, purchases are in ready to submit) - waited - reinstalled app, cleaned solution, all the voodoo stuff

Answer 1

Make sure you have signed out of any production iTunes accounts on the device.

I was getting this error on my test phone which was logged in with my actual iTunes account. You cannot test apps using your production iTunes account, hence the error. I just wish Apple provided a better error so as to avoid this guesswork...
