I’m encountering an error with Unity notifications. Below are the AndroidManifest.xml and the logcat error message. I’ve tried searching for solutions, including configuring Proguard, but It’s not working

I’m using
Unity 2022.3.0
Mobile Notifications 2.2.0
Just in case, I’m using firebase, too
This is a new safeguard in latest version of the package. If your app has multiple activities and none of them is UnityPlayerActivity (happens when you extend Unity activity), we require you to explicitly set the activity in settings.
In previous version it would work fine for as long as app is running or in the background. But if you killed the app completely, your scheduled notifications would not arrive. Now we fail early so you know of the problem in advance.
Go to project settings and in the mobile notifications section provide the full class name for activity you want to open when notification is tapped.
Any other ideas? I have done this and it got the error below. I then manually updated the androidmanifest.xml to the content in the text document for firebase which overrides it and I get the same error. I can’t shift it.
I am using both Unity Mobile Notifications (for reading state etc) & Firebase Cloud Messaging (for sending and receving remote notifications)

You must have messed something up in the manifest. Build apk, open it in Android Studio and check the final manifest. Most likely the metadata on custom activity is either not in there or is in the wrong place. Custom activity should be a meta-data element under application.
