I keep getting this warning message when I was building my App with GoogleMobileAdsMediationAppLovin. It seems its trying to find an Applovin precompiled header file from '/Users/thomasso/'. However, I have no idea where does 'thomasso' come from.
I am currently running with Google-Mobile-Ads-SDK (7.43.1), GoogleMobileAdsMediationAppLovin (6.3.0.0) and AppLovinSDK (6.3.0). I have checked my 'Apple Clang - Language' Precompile Prefix Header row and it's set to No
warning: /Users/thomasso/Library/Developer/Xcode/DerivedData/AppLovin-bwbdusdjdlnonrfwpebkwzrtnsop/Build/Intermediates.noindex/PrecompiledHeaders/sdk-Prefix-bolhsipvvnlaapgcaksiouwnzzai/sdk-Prefix.pch.pch: No such file or directory

the warning is fixed with AppLovin's iOS SDK 6.6.0. You will have to wait until AdMob certifies against that version to have the warning removed.
