Recent troubles with route preference in Route Builder

Has the router behaviour changed recently? This week it’s been infuriating to use because it seems to be preferentially choosing trails & sidewalks over roads. I’m having to constantly undo and redo each section because it seems to be actively avoiding running down the middle of the road (haha, which admittedly for most route builders would be a sensible default, but not for this one!)

I use Navigation & Routing APIs | Stadia Maps set to ‘pedestrian’ under the hood in Route Builder, so maybe they had a recent change.
