Your profile frame in SongPop can now be viewed in SongPop Classic as well!
In order to do so, your SongPop Classic account must be linked to a SongPop account. You can learn how to do this here.
In addition, you need to have a frame equipped. In order to equip a frame, go to your profile page and click on "Frames" under "Collected Items".
From there, you can select the frame you want to equip and it will be visible on your profile picture in both games! You can learn more about frames in SongPop here.
Once your account is linked, you can click on "Badges and Frames" on your profile page and enable the display by toggling the button.
