I have the exact same issue. ‘Power of the Primus’ shows up on my minimap but I cannot aquire the quest. I even see a silver question mark from the quest giver but no quest in their dialogue. It’s almost like it’s acting like I haven’t met a requirement to pick up the quest.
Because of that I cannot get my soul bind or daily we quests from the covenant hall. I can continue the mainline story quests so far but I know I’ll hit a roadblock once I get to Securing the House.
