HomeKit notifications only on iPad, not iPhone

homekit notifications will only show on my ipad and not my iphone. how do i fix this? when i locked my front door it sent a notification to the ipad saying the front door has been locked. i used to get these notifications on my iphone months ago but they've since stopped. my notifications settings look normal.
