Try doing it once more and see if it unlocks. If it doesn’t then contact support.
It’s sequential, you can’t skip the first step and get the subsequent rewards
My fault it worked after I had to redo the quest which imo shouldn’t be the case… thank you either way!
You used to have to actually CLAIM them each time, before doing next one, (actually press the CLAIM, or from stash).
Now at least you can queue up several completed levels, without CLAIMING them as you go.
But you still have to *DO them in sequence.
