Yes I’m using the correct package name of Messenger
This is the package name of Facebook app not Facebook Messenger App
Of course Yes it’s installed in my device
No i didn’t use activity starter solution
I think the main problem is Your extension is made for old Android version because you didn’t updated your extension after 2020 ao that’s why it’s not working in Android 11,12,13 version please provide updated version of this extension for higher Android Version if possible Thank you
