Health app/activity app not syncing

Hi. I can no longer get my Apple Watch to sync with the health and activity app. My watch won’t show as a data source in the health app. I started by restarting, repairing etc. I tried backing up and resetting my iPhone, resetting my Apple Watch. Turning off all the motion and fitness data, airplane mode. Everything I read online I’ve tried but the watch still won’t show as a data source, the sleep app isn’t tracking and activity isn’t tracking on my iPhone. It is tracking on my watch though. Any ideas what to do next?
