Hello I’m in the middle of replacing the feet on my A1502 model as per the instructions at MacBook Pro 13" Retina Display Early 2015 Feet Replacement - I’ve just completed step 7 to remove the adhesive and noticed under that is what appears to be a clear sticker between the foot and the case itself - one of these has been damaged slightly as a result of cleaning. My question is - does this clear sticker need to be removed also before installing the new feet? Thanks.
That clear sticker is most likely the old dried adhesive to hold the old foot on.
