All of the sudden remove ads in-app purchase and restore purchases don't work in my Xcode projects created with Buildbox. Not sure if this is a bug in BuildBox or a problem on Apple's end. Everything worked before of course. If you tap on a restore purchase button it says "Restore Purchses Error". If you try to do the in-app purchase it says "Transaction Error: Cannot connect to iTunes Store". This is on device. Just to note - the other apps installed on my device work fine. This is only impacting apps created with BB.
Check your agreements in iTunes Connect. There is one (or several) that say REQUEST. Do that and everything goes back to normal.
