So the video @glauberkelvin posted is essentially the exact same experience I'm getting in 2023 using Next. I've posted a separate post and then stumbled on this one. The video is my exact experience when I preview on another browser. I was hoping it was the incognito/guest cookie issue, but it doesn't seem to have fixed the issue. I looked at the cookies and I do see a cookie set for io.prisimc.preview. Unfortunately, the content remains as the currently published version.
