I was running into the same issue. Turns out my user wasn't the "Account Holder" (you can see that in the AppStore Connect = "User and Access" screen) so I couldn't agree to the terms myself. The "Account Holder" user could login and accept the terms.

Hi, We were able to get a live postback at Singular and successfully validated its signature using the steps described by @fruitshake. It looks like the current example in Apple’s documentation doesn’t have a valid signature, but the real signatures work as expected. We wrote a blog post on how to test SKAdNetwork - check it out at: singular.net/blog/ios14-skadnetwork-test-setup Hope that’s helpful!

Following-up on our original question, we were able to receive SKAdNetwork postbacks and wrote a blog post about our test setup. Check it out at singular.net/blog/ios14-skadnetwork-test-setup Hope it can help anyone!
