Were you able to find a solution?
No not yet. I have managed to get notifications to work using the older version of the plugin push. (1.9x branch). However, I really need to use the 2x version so that I can take advantage of the newer android builds (the older ones are no longer accepted on the play store).
What I really need is step by step instructions of the config needed to use the plugin push 2x branch with PhoneGap Build for both Android and IOS.
There does not seem to be any substantive guidance on this. For example, we know that to use FCM we must download the json config file and put it in the root of the PhoneGap buld project. However, What config options do we need to reference this, do we need to change any of the json in the config file itself?
From what I can see, we really need to be using the 2x version, so we really need a step by step on how to make this work with PhoneGap Build.
The documentation provided is simply not up to scratch...
This forum seems to be a black hole and there are no other support options available. I am not sure phongap is a valid solutions anymore
