Fitness app problems on iOS 16

So I got a unique issue here.

As of a couple weeks ago at work there are now long stretches of time were I can’t wear my Apple Watch.

I figured no biggie though the new version of iOS will have advanced fitness tracking, so I can accurately record my activity during my shift even when I can’t wear my watch.

Im constantly moving for upwards of 10 most days.

Now most days I have to put my watch in a locker. The thing is though I think the activity app is still trying to pull the activity info from my watch and not my iPhone.

As I said, I’m on my feet for my entire shift. It doesn’t make sense to me that the activity app on my phone says I’ve been standing for two hours when I have really stood for over 8.

Do you think this problem could be solved if I turn off my Apple Watch before I start working? Or is the fitness app just not working for others as well?

both my watch and iPhone are up to date
