Isle of Thunder solo scenarios not working?

Title. I tried queuing for “The Assault on Zeb’tula,” but I was never brought to the instance, and the queue went on and on without finally putting me in. This is very upsetting, since I’ve been spending the past month-and-a-half trying to experience Mists of Pandaria like a solo game, patch by patch, getting Loremaster, doing the Domination Point questline, and now I can’t progress proper because this bug. Is there any way to get around this? :disappointed_relieved:
