Hey, I could not find any info/documentation about setAdImpression: method of SKOverlayAppConfiguration (https://developer.apple.com/documentation/storekit/skoverlayappconfiguration/3951377-setadimpression?language=objc). When exactly should SKAdImpression be set to the SKOverlay object? Is it related to fidelity type 0 postback? Currently using SKOverlay we get only fidelity type 1 postbacks. Any info will be very appreciated. Thank you!
