Screen time records apps that aren't open
I have screen time set up on my phone, track across other devices is turned off and yet it still shows more screen time than I'm using on my phone. When I check, it shows Settings is on for hours and so is Instagram. I have Instagram on a 15 minute setting and I close it when I hit my limit. Is there some setting or something I'm missing? All other apps seems to be representative of my usage, it's just these two.
Thanks!
