I am having the same issue on a running iPhone. Others have reported the same at https://developer.apple.com/forums/thread/836787?page=1#903293022 @Frameworks Engineer Do you have any other suggestions?

I am also experiencing this (though I'm using Unity IAP, not StoreKit directly). Clearing purchases locally and in cloud, then signing out of Sandbox account and restarting/reinstalling the app: my fulfillment logic still being triggered for previous purchases. :( @newwbee That link is showing "Feedback Not Found" FYI
