System Services using all my data after iOS16 update
System services is constantly using my data when I'm not connected to Wi-Fi, I've had to add 2gb extra last night and I've now got 59mb's left. I've tried turning off automatic updates etc but nothing seems to be solving it. How do I stop this as I currently can't have data turned on, which is not great when not connected to Wi-Fi.
See screenshot of data used after literally 5 minutes after I reset the statistics.
iPhone 8 Plus, iOS 16
