The medal is pretty egregious. I would say it’s more than a decent jump you have to make to get from Leia holding the medal to Han appearing a few scenes later. The dice in TLJ works because you clearly see it is something that belongs to the Falcon, and therefore is Han’s. Obviously if you’re a fan who knows the dice are in ANH, or if you watch after Solo, it works even better, but it still works without that. The medal, we are given no indication that it is specifically Han’s. In ANH we see at least Luke get one as well. If you don’t have a good working memory of ANH (enough to know what a prop from one scene looks like), you won’t recognize it. Even if you do, there’s at least three different steps you have to make in your own mind (with no help from the film itself) to reach the outcome of Han appearing to Ben.

I don’t begrudge anyone wanting to include the shot, especially if you’re still keeping Chewie getting the medal at the end (anything to make that scene better). But this is another case of ‘they cut out all the scenes that explained this.’
