    Hi! I'm an engineering student and GSoC applicant looking for a good first issue, and I would love to tackle this one.

    It looks like the banners.dismiss endpoint/method is throwing a banner-not-found error behind the scenes. It seems the backend is strictly validating the banner against the global Banners collection, but failing because the 'new version' notice is a user-specific system banner. I plan to update the backend logic in apps/meteor to correctly validate and mark these user-level banners as dismissed without throwing an error.

    Could you assign this to me?

    I have solved the issue on my end and will make a PR soon.
