I submitted some Advanced App Clip Experience details via the App Store Connect tools. The URLS are in a status that says "received". What is the next step? What does this process really do? Thanks!

After upgrading to Xcode 12.5 and iOS 14.5, I can no longer debug my app on my local physical device. I get the below error. I searched and cannot find any answers. How do I fixed this?
