Blissey ability not working

jasmine1234567

I was using a deck based on the let’s all rollout attack and I was playing against a mew vmax deck and blissey’s ability wasn’t working and the mew vmax was just taking straight knocks even though it was displaying all the little green triangles. am I missing something that was turning the ability off or was this a bug?

Mew VMAX's second attack, Max Miracle, ignores all effects on the opposing Pokemon, including Blissey's ability. Intended behavior, not a programming error.
