Yep WkWebView.load(URLRequest) in a UIKit app causes this issue for me in the Xcode 14 RC.

Update It turns out that if there are two Transaction.updates observers in an app it seems to only return the updates to one of these! When I get rid of the other observer it works fine... why?!

actually ignore above comment, still not working correctly. Any help?

@khagan Yes your issue is exactly the same as mine. Unfortunately I couldn't figure this out and no help from Apple! I had to ditch StoreKit 2 in favour of StoreKit 1. I reproduced the bug in Apple's own sample app. Maybe you could file a bug report for this and link back here with the report number?
