hi, i had purchased UTnotifications and works ok. But when i add google admob plugin (https://github.com/googleads/googleads-mobile-unity) i can't compile: "FileNotFoundException: Could not load file or assembly 'GooglePlayServices' or one of its dependencies. The system cannot find the file specified." I try to modify androidmanifest.xml but nothing works to me. May be is a problem of duplicate Gooplayservices library? or something i cant see? Thanks, Angel.
