I got a solution that worked for me: Open up build.gradle (app module) And find **dependencies**. Replace the versions (that are most likely stated as "+") with: ``` compile "com.google.android.gms:play-services-tagmanager:16+"...

@daithi-coombes You can also try to change the plugin.xml for the plugin and set the versions to: ``` com.google.android.gms:play-services-tagmanager:16+ com.google.firebase:firebase-core:16.0.8 com.google.firebase:firebase-messaging:17.5.0 com.google.firebase:firebase-config:16.4.1 com.google.firebase:firebase-perf:16.2.4 ```

@outspokenmagazine Don't forget that the --save does overwrite other custom made changes. What i did was: 1. edit the versions inside plugin.xml 2. edit the versions inside build.gradle (app module)...
