why did my watch close all rings when I was riding in a car for 12 hours

Hi maryb20, We appreciate you reaching out to us. We understand that all three rings on your Apple Watch closed even when you are riding in a car for 12 hours.

We’d like to gather additional details that may help us be in a better position to assist you. Is it possible that an Activity is running while you are driving?

Are you sharing your Apple ID with another person who is also using an Apple Watch?

If no, we recommend that you unpair your devices, then pair them back again.

Below are some articles to guide you through the process.
