On two macs with 10.15.2 (19C57), we can't test an app for in app purchases
# Steps
Build App in Xcode
Launch App from Finder
It launches, and quickly closes
After a slight delay the sandbox Apple ID is requested (we expect this, as it needs to fetch a sandbox receipt)
Enter a sandbox user Apple ID
# Expected (it used to work)
The os fetches a sandbox receipt for the app
The app launches
# Actual
The System dialog comes claiming the app is damaged and needs to be deleted and redownloaded from the App store
When launching the app again, gatekeeper "verifies" the app and comes to the same conclusion.
In the app, there is no MASReceipt
Any advice?
