No Market Tab (Currently in Endgame)

I'm currently experiencing an issue in Path of Exile 2 where I do not have a "market" tab. Looking online, I was supposed to obtain this after completing Act 4. However, I have completed all quests for all the Acts including Interlude and am onto the endgame. The tab simply does not show up when I pull up the selections menu or hit the typical "/".

I also do not have access to my merchant tabs from Ange in my hideout either. The game is acting as if the quest was not completed, however I have absolutely progressed beyond it / completed it.

Please help as this is extremely frustrating!

OMG this was it. Thank you so much. I clicked the SSF league without realizing what it actually does. Converted my character and am now back in business
