This Issue is presentient with all phones above 11, The glass material looks totally looks fine in iPhone 10,7,8 etc... Please fixe this issue for Apple's AR views. We thought that maybe there is something wrong with the file format but This issue is only present is iPhone 12 and above.

We Tried to find work around but after doing multiple test but with all our experiments we came to the conclusion that Apple AR viewer is not able recognize the glass material and adjest the ground shadow as required.
