SKProductsRequest not returning in iOS 13 Beta

In all the iOS 13 betas so far up until beta 6, when testing my app in the Simulator I get no responce from the SKProductsRequest start call.

It works fine when testing on a device, and it works fine when testing the MacOS version of my app, it's just the iOS simulator not returning any available purchases.


Is this siply a restriction of running a beta, or could this be a problem?
