Native Linking Failed MT5210 with Firebase Remote Config on iOS

TheGX2TheGX2 ✭✭USMember ✭✭

I have Forms project the when I add the Firebase Remote Config package from the Xamarin Component store and follow the sample code I get 21 Native Linking Failed issues. Below is my output on Xamarin Versions and Build Log. Any suggestions would be greatly appreciated.
