iPhone no longer tracking steps/movement

iPhone 13 stopped tracking steps. Using iOS 17.6.1. I’ve deleted and reinstalled health and fitness apps. The fitness app resets every time I close it down, and prompts me to set us as new/asks me to enter personal info. Apple has been zero help after 3 calls.

Apple watch tracks movement, not nothing synchs to my watch like it used to. I’ve unpaired and tried to use phone for steps independently and that doesn’t work either.

Fitness tracking is on under motion and fitness in settings.

Have other had this issues and resolved without having to erase the phone and start over?
