Saw this on my ipad too. It was the iMovie icon though. Turns out that it’s Siri thinking it’s the time you often use that app and suggesting it for you. Saw a similar question somewhere on apple support pages.
This is done exclusively on device. No information for his function ever leaves the device.That’s kind of weird in an unpleasant way. I really dislike all forms of tracking. Do I really need an app to tell me when it thinks I might like to use it???
Are we all becoming that brainless and dependent on technology that we need it to tell us what to think?
