We've been using the Playfab Android Push plugin, but ran into a bug recently that's setting us back (different thread). One of the things we've been discussing is if there is any reason why we should not implement a different GCM plugin (such as Prime31's since we already use many of his plugins). I know there are a few interconnected pieces, and maybe for local push it's a requirement to use the Playfab version, but we're not doing much more than API generated push messages to the client. Just wanted to throw this out as a general question before we make any changes.
