Hey just found this thread because I was wondering the same thing when looking at my Data & Sensor access.
For everyone who is insisting that it has to do with the shortcuts app— I am an avid shortcut enthusiast and actively use the app. As you can see in my screenshot this is something separate. It raises red flags for me because I'm familiar with the ongoings of my phone and am fully aware of every shortcut I have; how and when they operate.
I do not have any shortcuts that call on contact access nor would the sharing of contacts EVER take place with the shortcuts app unless triggered manually or via automation by the user. As you can see in my screenshot as well, the frequency in which it happens on seemingly randomized times and dates is definitely something worth looking into or else I wouldn't be here.
It takes a special kind to be so naïve as to think Apple is truly impenetrable and then use that closed off way of thinking to condescend to others. Its pretentious c*nty behavior at best.
But don't mind me, it's probably just the aluminum toxicity from my foil hat speaking.
