I started working for my iOS 12 and 13 testers this morning EDT. Whew... Thanks Apple for getting to the bottom of this!

Same here. In-App dialog is showing twice, after that it fails with error "Cannot connect to iTunes Store". Multiple users and devices. iPad mini iOS 12.4.8 iPhone X 13.x? tester Xcode 11.3.1 OSX 10.14.8 Waiting for a iOS 14.x tester I can retrieve the description and price. I present the user with a dialog before I start the purchase process. So I can communicate to the iTunes store but can't complete a purchase in the sandbox. I have the distribution version waiting to be released but I'm afraid that all the users will start calling. How can this not be addressed ASAP? I'm dying here...
