I think that the policy of every Apple store is clearly stated on Apple's website, and since it is different from state to state depending upon local circumstances and guidelines, some stores are probably scheduling shopping sessions, and others are not.
I've made several trips to the closest Apple Store over the past month or so, and they have been terrifically polite and helpful. Once for a genius bar appointment and to have my iPhone diagnosed, second visit to bring the phone back for repairs after parts were received (this second visit included a reservation for shopping session so my wife and I could look at new stuff), third visit to pick up a new iPad and drop off my trade-in.
One thing about this current arrangement is that you have someone dedicated to helping you while you are at the Apple Store, whereas back in pre-pandemic times you could browse without an Apple specialist, but then getting one to answer questions might take some time depending on how busy the store happened to be at the time.
And it turns out that since the situation in our part of the world has deteriorated since my latest visit to them, my closest Apple Store is not currently supporting shopping sessions, only Genius Bar support by appointment, and picking up online orders:
Apple Store River Park Square store hours, contact information, and weekly calendar of events.
