I think the reason why they're not aggressive enough is that they just keep swooping up and down vertically. Increasing as time passes. This might affect their behaviour towards players, but I'm not 100% sure.
This could be because mobile players doesn't have the same reflexes as PC players because controls are harder on mobile.
No@Chiseled Stone Music, even if it is on mobile it takes 2 and a half minutes before they aggro on a player again after it has been summoned (Well, that's even if they attack once they've been summoned). Look at this. Note: I've given myself strength but it seems to weaken my attacks? Plus the Evoker takes an awfully long time to summon the Vexes.
I understand, but please give the devs time. What is happening is that they're prioritzing on bugs to fix and yours might be lower on the list. I'm sure they will eventually get to contact you about the status of your report.
I've played the Java edition of Minecraft and apparently they swoop behind you very fast. Also they should move their left hand while attacking. While they are not attacking they should move their arms and legs because they don't do that.
