I have an app developed in IONIC v1 and I am using phonegap-plugin-push to receive notifications, my current plugin version is 1.3.1 and when I am checking on Android 8, 9 then I can see that notifications are not coming.
I have checked this plugin's repo and I have read that we need to upgrade this plugin to latest version so I have upgraded plugin from 1.3.1 to 2.1.3 version but my IONIC version is still v1. Ever since I have updated plugin I am getting this error "INVALID_SENDER"
Here are more details:
cordova --version 9.0.0
cordova platform version android 7.1.0
So, main issue is that I have an app in IONIC v1 and I want that users of PIE & Oreo should also get notifications. I don't want to convert whole app to IONIC v2 or v3
