Hi
If it is not yet enabled, it may help to turn on Background App Refresh for the apps in question:
- On your iPhone, go to: Settings > General > Background App Refresh.
- Turn on the main setting at the top of the page.
- Check the settings per app.
It may also help to check the following setting (in addition to the Location Services settings for each app):
On your iPhone, go to: Settings > Privacy > Location Services > check that Apple Watch Faces is set to While Using the App.
