Hey! Welcome to the community 🙂 

Do you have activity sharing enabled in Edit > Preferences > Acitivity Sharing > .... To Facebook? 

Facebook have strange ways of rolling out new features, this is not something I have ever come across on my Facebook so maybe your friend has a new feature which you do not have (since there are music changes ongoing on Facebook!).
