if you haven't already, i would work on training a cue for potty. Others may have a better way to training this but something like saying "good potty" every time they go and rewarding. maybe try to say "potty" (Or whatever word) when you see they are about to go (about to squat) and then reward.
you can use any word. unfortunately i always pick "peepee" haha.
sometimes removing toys helps (they come out when you play and are put away when you come back in).
we do potty walks in the morning. even in the rain/winter i do go out with my two to get them to pee. Rock won't go outside without me
