Ultron not immune to slow

After Ultron's buff, he's supposed to be immune to slow but when I fought him in the side quest, I was able to slow him.
Fighting him in a duel confirmed this. You can slow him and while he is slowed, he cannot evade even though the evade text pops up.

"True Strike - IGNORES auto-block, evade, armor rating, and resistances (physical, energy)
True Accuracy - IGNORES auto-block and evade
True Sense - IGNORES auto-block and miss
Vigilance - IGNORES miss
The ignoring part is super important as it essentially states that regardless of those abilities' ability accuracy, they will not trigger. It also means that none of these abilities are affected by ability accuracy."
The "NOT TRIGGER" part of the statement is not accurate (pun intended).
I replied:
"They will/can still TRIGGER these abilities, they just FAIL to work.
I know it's a bit splitting-of-hairs but with AA verbiage like updated Ultron stating his AA can't be modified from TRIGGERING his effects, it doesn't mean they should actually WORK if he's slowed, fighting a true strike/accuracy champ, etc., right? There's another ticket for Ultron not being able to evade with SLOW debuff and the confusion appears to be that his evade mechanic is still TRIGGERING which is AA that can't be modified, HOWEVER, if slow debuff is on him, it should not WORK (i.e., actually allow him to evade)."
There's a difference between TRIGGERING and actually WORKING. For example, when you fight an auto-block or evade champs with Killmonger and true-strike is active, their abilities STILL TRIGGER and you can see it trigger - it just FAILS.
Here's my take on the updated Ultron confusion. Because Ultron's abilities (and damage build-up) rely on his functions TRIGGERING, Kabam made it so that his ability to trigger the functions is immune to AA modifications so they will always TRIGGER. HOWEVER, as stated above, TRIGGERING does not necessarily equate to the ability WORKING if it's being countered by slow, true-strike, true-accuracy, etc.
Just my .02
Overseer has just autoblock which gets bypassed with strue strike/accuracy but whats happening on overseer is that hes preventing the true strike/accuracy to bypass it even though its just a normal aut block mechanic which be bypassed if angela is at x buffs or true strike is active
I'll leave now.
