camera scan QR code does not work after deleting app clips

We removed the APP Clip feature in the latest version, and our server-side synchronous update the "apple-app-site-association" file, remove "appclips" content.

now, i use Camera app scan the QR code(regardless of whether the app is installed), the following error occurs:"This app clip is not currently available in your country or region".

I checked some information and it might be due to Apple CDN cache, or is there something else I need to do?
