I've checked your news and PA did say purchase of the premium pass would be available on the 28th of December. It's the 29th and you still haven't fixed it. And if I want to get to the Black Spirit Mission Pass Event tab I have to do it through Daily Tasks and click on the little bar on the top right of the screen. Before, I got confused and just went straight to the event button and Black Spirit Mission Pass did not appear, still doesn't appear if you got directly to the event tab. I WANT to purchase the Premium Pass to get the new shark outfit but you aren't letting me.

I'm also having the same issue unable to purchased

Same here and I'm accessing it through the same path - menu-tasks and it's not available for purchasing.

Can't purchase black spirit mission pass...
