Hi, there is a problem when I use Evoke (also I saw content creators with the same issue) and I try to use the artifact Springleaf Drum to use the creature (Emptiness - Elemental from Lorwyn) but the game do not let me activate artifact habillity in the stack.

Please try to check it, it works when I can play an instant for example, but if I try to generate mana to use after the Evoke action, it's not allowed to do it.
