It seems indeed, or so I missed something (if someone can confirm)
Confirmed 🙂 There are no settings in the ACP in v3.
As you might have seen I released the NodeBB WebView app, which uses OneSignal. As of now you have to send push notifications manually, which means that users will not receive actual notifications from the forum itself. Due to this I request a OneSignal integration with NodeBB.
Things to consider while creating the plugin:
Every user needs an unique ID. Otherwise notifications directed at them will end up on other devices as well.
