Yes, there is still the final step of having a CM scan your QR code and offering to bag up your items. Depending on the store, they are either positioned well (right at the exit, as you would expect) or some random place in the middle of the store (I'm looking at you. World of Disney). Either way, the signage seems to have improved compared to last year.
I think for someone buying multiple items, it feels stressful. I have to stop to the side, place all my stuff down, individually scan every item, pick them back up again, and walk to the mobile checkout area only to have to pull up a QR code while juggling holding everything. Since there are no defined areas to stop and scan your items, in a crowded store I often feel like I am just in the way of people browsing.

For one item though, it is usually a better experience.
