I googled around and found a couple reddit threads with people reporting the exact same thing starting 2 or 3 days ago. There were reports from people on iPhone 12 and iPhone 17 so it doesn't seem device-specific.
Anyone else seeing this? Does anyone understand how or why this is happening?
An app store search also turned up "Headspace Care" (Ginger)
Ginger is now Headspace Care
It would be beyond malware for an app to install itself, since there's that app store hurdle to leap. (IMO)
