Universal App Linking is not working on devices greater than iPhone 11 with 15.5 iOS?

We are developing an app using flutter, and we have also uploaded apple-app-site-association. The universal link is working fine with iPhone SE (15.5) and iPhone 8 (15.0). However, it's not working with iPhone 8 15.5, iPhone 11 15.5, and iPhone 13. Please take a look into this issue and let us know any help on this. Thank You.
