I've been waiting well over ten minutes after trying to create a Jira site. The page keeps flashing the same two messages: "Working on it..." and "Loading..."
I saw this same question asked back in February with an answer saying to try using the name I created the site with and see if it'll load. (e.g. xyz.atlassian.net) Unfortunately for me, this didn't work. It appears as if the system is stuck trying to create this site.
I tried disabling my ad blocking software (I'm running Chrome) to see if that would affect it. Unfortunatley, it's still stuck. 
Any help would be appreciated!
