Supposedly the brawler's guild isn't working during shadowlands.
When you go into the Horde Brawler's Guild, the grunt patrolling the front tells you the guild is closed.
However, if you go to the back and speak to the female grunt or the male grunt by the bar, you can queue up for brawler's guild fights.
This can be useful if you have a ticket but are still missing items such as Clock'em, Tyler Gronnden, transmog or the Brawler title.
