Recently I have gotten into a Unity project designed to run on iOS, Android, WebGL, Amazon Fire, and Facebook app. The previous developers said they could not use PlayFab for push notices because PlayFab would not support Facebook apps. (At least I think it was Facebook it might have been WebGL in general or Fire version of Android? I am forgetting now.)
Are there any known issues with push notifications, in Unity, on any of these Platforms? The code is a bit of a YAS (Yet another SDK) mess and I would love to pull out the other push notification system if we really don't need it.
