Renown and progress locked / TWW

So I completed the leveling campaign in TWW, got achievements for it and everything, unlocked the factions. Yet the other day The Assembly of the Deeps faction became locked. Hovering over the faction in the in game menu tells me “Complete the quest Back to Gundargaz in The Ringing Deeps”. Thing is, I did! Even after submitting a ticket, a GM got back to me saying they are confused or something because the quest I’m referring to doesn’t unlock the faction. Yet that is what I’m being told in game. I can’t continue the TWW campaign because it says I need to reach renown 4 with each faction before continuing, but it seems I’m not getting credited for renown and I have no way of tracking it. I’ve gone back on every character I have brought into TWW and no sign of the quest anywhere, not available to grab, not in quest logs, nothing. This is absolutely frustrating me to no end. GM stated everything should be working normal and on their end there is no issues, yet here I am. I even provided screen shots of what I’m seeing on my end.

Am I the ONLY one experiencing this!?

I am experiencing the same issue - I cant get the quest “Back to Gundargaz”. If i click on the city Gundargaz on the map it says I am at renown rank 1. When I click on my Khaz Algar summary, it says the Assembly of the Deep faction is locked. Very frustrating…

I ended up having to redo the The Ringing Deeps storyline and complete the quest again for it to credit me. Pretty stupid but it worked and thankfuly doesnt take too long. Just went on a fresh 70 and choose the ringing deeps to start questing.
