Fitness app is no longer tracking my daily steps data
I have an IPhone 15pro with the latest system update available. The Fitness app used to work but for some reason no longer tracks my steps and movement. I did find some AI generated solutions to try- making sure privacy and security settings are correct for tracking health data and toggling switches off/on, restarting the phone. Nothing I have done resolves it. Also I can see the exact day it stopped working, about week and half ago. Help please?
iPhone 15 Pro, iOS 26
