Siri Sources Have Moved
If you’re a fan of the Siri watch face, you may be perplexed to discover that there no longer appears to be anywhere to switch individual data sources on and off. For example, if you’d rather not see cards for photo memories, or you want to switch to an alternative weather app, these settings could previously be found in the configuration for the Siri watch face itself.
Don’t despair, however, the settings are still there, but for whatever inscrutable reason, Apple has chosen to move them to the general Clock settings in the iOS 13 Watch app without telling anyone.. You’ll find a new section at the bottom named Siri Face Data Sources that provides all of the same controls as before. As an added bonus, it can also be found in the same place in the Settings app on the watch itself now too.
When it comes to privacy, Siri watch face cards are also subject to the same treatment as complications, which means that if you enable Hide Sensitive Complications in Settings, any potentially sensitive Siri cards will be hidden as well wherever you lower your wrist, although as with complications, your mileage may vary when dealing with third-party apps.
