Yes! I have just done this and also had the same issue. In step 19 you can see a black plastic trim stuck to the removed screen - this had detached from the (very shattered) glass and was left in the frame, which I did not realise until trying to put the new screen in place and wondering why it did not click into place. Once I removed that and spent 40 mins cleaning up the next layer of adhesive, the new screen popped in perfectly. The bit remaining was the 'entire perimeter housing' as mentioned in the comment
