App Clip Card - This app clip is not currently available in your country or region

I am testing App Clip on Testflight to show App Clip Card but it only shows a white Card with the message: “This app clip is not currently available in your country or region” (if using Local Expreriences, it shows normally) I have fully installed apple-app-site-association, App Clip Experience, Domain URL Status also validated ... don't understand why, is the app "Redy For Sale" new to show the Card?. I want to let customers test show App Clip Card without using Local Expreriences on Testflight If anyone knows, please help, thank you.
