hi, we are experiencing similar problems with our app. We went live 2 1/2 weeks ago and the in app purchases are not working. We paid a developer to build our app, we ourselves have no idea about coding etc. what we are finding, the in app purchases are being deemed as successful, but then the user is not receiving the upgrades. We have four devices, iPad 4, ipad Air and 2 iPhone 6's all with iOS 9.1, we have family sharing on all devices, we have ourselves tried to purchases the upgrades using our own devices. Initially none of the devices received the upgrades, however restoring the purchases (several attempts) finally worked on the iPad 4, so we have the full upgrade on that device, however we cannot get it on any of our other devices. It's telling us the purchase has already been made and will be restored for free, but it's not restoring on the other three devices.... which again have family sharing... This is very frustrating as we are getting complaints from angry users and rightly so, they are not receiving what they paid for! Apparently the in app purchases were working in Sandbox, but when the app went live its not working! I don't know if it's a source code issue or an ios9.1 issue, we have been trying to submit to Apple a TSI without much success and we are still waiting to hear from our developer. Any advice would be greatly appreciated!
