how do i hide this spotify app activity from my profile on facebook ?

[CRA]

ok so i have this app from facebook downloaded so i can listen to music, its called spotify, You listen to a song and it puts it on your facebook profile like for ex; "so & so, just listened to this song" and i used to be able to click the the x next to it & decide from "remove spotify" or "hide this action from profile" and either one would hide/delete the post from my profile.... but for the last couple weeks, either choice says " oops something went wrong, we will get it fixed as soon as we can" but i really dont want it on there so i was wondering if there was any way possible to get it off of my profile, please help!?

Click the white "Profile" link near the upper right corner of any Facebook page. This link is between "Home" and "Find Friends." This takes you to your profile page, where you can view your wall.

2
Scroll down on this page until you see a message from an app.

3
Hover your mouse cursor anywhere over the message from the app. You should see a small, somewhat faint X appear in the upper right corner of this particular message. Click the X.

4
Click "Hide all Platform activity" in the list of options that appears. Your other option is "Remove Post," but this only removes this individual post instead of hiding all your app activity.

5
Click the blue "Hide all" button in the small window that opens
