hill assist light comes on but not engaging

I haven't broke any break lines. I did a rear tire change about 2 months ago and every since then the hill assist isn't engaging. I activate with the front brake as usual. The light turns green but no brake engagement.

Try using the rear brake alone for a few stops, then try the brake hold again and see if that wakes it up. It's possible when they installed the rear wheel they spread the pads.

Tried that with no result. Gonna bleed back brake i suppose. Not sure that'll fix it. I removed the rear wheel for new tire install and no brakes were manipulated or lines cracked.

I took the wheel off when I got the new tire. No manipulation of any brakes or lines when I did that. I did notice after the tire was back on that the rear brake felt mushy (indicator of possible air) but would tighten up when pumped a time or 2. I can't figure out how air would have got in the line. Subsequently the hill assist light would come on (green when front brake squeezed) as if it was operational. Still no hill assist. Sometime the light will be orange when I try to apply hill assist indicating and issue but on a following squeeze it may go green again with still no hill assist so it's just being funny I guess. I don't use it really either but I'm aware its acting odd. Will keep troubleshooting.
