Just switching the order of the plugins in the build settings and removing supportedPlatforms line so it matched the sample in GitHub as @agramonte suggested worked for me.
Not sure what the implication of removing the supportPlatforms parameter is?
The parameter exists to keep you from loading Android only plugins on Apple devices and visa versa.

Thanks Rob - When I removed this parameter my code wouldnt build correctly for iOS so I’ve added it back in and everything is ok.
