Bug in hero's journey event

I'm also facing this problem 

Hey there. Thanks for reaching out and reporting this. To look into the issue properly, we’ll need a bit more information: where exactly in the event you get stuck, what happens when you try to continue (for example, does a task not register, does a button do nothing, any error message), and whether you’ve already tried things like restarting the game or device.

If you can also share a screenshot or short clip of what you see when the bug occurs, that would help a lot in narrowing it down.

I have finished the achievement with the first 6 players but the lock doesn't disappear and this is the second time completing it . what's going on 💔
