The same problem. The latest available version of GoogleMobileAds-native does not work with Play-Services-20.0.0. But this works fine with the Play-Services version-19.7.0.

Play Services Resolver automatically integrates Play-Services-20.0.0 version. And it does not allow to roll back.

We need an updated version of GoogleMobileAds-native with support for Play-Services-20.0.0. But I couldn't find it. Maybe they forgot to update it.

Please update the GoogleMobileAds-native plugin. I have been waiting for 3 months since 6.0.0 was released😥

[NVentimiglia]

GoogleMobileAds-native plugin support for Play-Services-20.0.0 is a priority.
