capacity full and registration unavailable

I'm just said, I got in queque pretty early and waited maybe a max of 10 mins ish? Honestly, thought that would guarantee me access at least to check out, but it only made me wait at a “registration unavailable” page for maybe 20–25 minutes until I finally got access to the registration page. I found out it was all sold out to expo but immediately reloaded page to not even be able to add the masterclass that was still available, I mean i totally understand the competition with everyone I just wish it had been more organized :(
