I’ve never used this plugin, but are you sure you did all of the other installation tasks in the ionic-native doc page, such as actually installing the corresponding cordova plugin and adding the provider to your app module?
Think of it this way. The person who opened that issue went to a restaurant. You phoned a delivery service that brings food from many different restaurants. At the end of the day, you’re still eating the same meal, although it has been presented in two different fashions.
Haha well I like the analogy but unfortunately I think neither of us are enjoying the meal. For some reason I think cordova isnt finding the “exec proxy” for FCMPlugin and that is the root of the issue. Any ideas? I tried uninstalling and reinstalling the plugin to no avail.
