Static site not properly updating

I have next JS static site and it’s configured to preview PRs, but when I look at the live PR server it shows the old code that’s currently on main. I saw other issues similar to this but I didn’t see any specific resolutions. Would it be better to just deploy the next.js app and run it as a server?

If this is still ongoing, could you DM me the site details and I’ll help take a look?
