purchased duskmourn mastery pass but only receiving free tier rewards
I purchased the Duskmourn mastery pass at level 25. It gave me all of the prior premium rewards, however levelling up further is only giving me the free rewards and not the premium ones. Missing the rewards for levels 26, 27 (400 gems + 1 mastery orb + Shrewd Storyteller skin). I have the video capturing the bug immediately after the winning game.

I have the same issue. I purchased the pass at level 31 and I received all the Mastery Pass items up to that point. Leveling up beyond that however does not give me the mastery pass items, only the free ones. I'm currently on level 38 and am missing all the items from levels 32-38.
I'm missing 3 Mastery Orbs, 3 Card Styles, 2000 coins, 400 gems, 2 random mythic cards, and a Duskmourn pack.
