I am trying to set up Google AdMobs on a project that I have already set Firebase up in. I have been trying to follow the Update your info.plist section of the AdMob documentation here: https://developers.google.com/admob/ios/quick-start#swift
but I keep getting the "reason: 'The Google Mobile Ads SDK was initialized without an application ID. Google AdMob publishers, follow instructions at https://googlemobileadssdk.page.link/admob-ios-update-plist to set a valid application ID. Google Ad Manager publishers, follow instructions at https://googlemobileadssdk.page.link/ad-manager-ios-update-plist." Error.
I am wondering if it is because my plist is named GoogleService-Info.plist rather than Info.plist (This is the name given by default when I first began using Firebase). If I try to rename the file to just Info.plist, the firestore part of my project breaks. Does AdMob require Info.plist to be named exactly that?
