It’s pretty frustrating to sign up for a SNG game and sit there for 20+ minutes because the site never makes your presence visible to other users of the site.

Refreshing the main lobby page doesn’t pull down correct data. You see tables with 1 empty seat remaining, try to sit, and registrations are closed and the game is underway. You see tables with 1 empty seat, try to sit, and find that you’re at an empty table because the other player gave up and left, but their ghost is still showing seated, even after multiple refreshing.

You refresh the page and try to scroll down, and the page continually re-draws the list of tables that are visible through your filter, to the point where the site is unusable for 30-45 seconds until the page finally decides it’s done reloading.
