A half an hour later the perk somehow got installed, but I don't know how or why, because I got fed up of following him around trying to figure out what was wrong. The janitor bots install their perks immediately (so far), but the guards still have a big delay for some reason.
(Please don't mark this as solved yet; the delay issue suggests there's still a glitch somewhere. I'll post more information here as soon as I have something. Thanks 🤖)

My robo guards still won't install their perks (not on my PS5 at least, unsure whether other folks have tested this on update 3.0 yet), though I've been told they do on PC.
Even when I use the old workaround of turning off their other tasks, they just walk to the furthest away plot doing nothing, and then come all the way back again. Putting them near the mod-stop machine also has no effect.
The janitors do seem to install their perks however.
Screenshots attached.
