Does anyone know why my son’s screen time is all gray? Also does not show any app usage. It says he’s been in settings for 3 hr when I am looking over his shoulder and see him in doulingo, games etc. I know some gray bars are normal for stuff running in background but shouldn’t be ALL gray when he is using apps. We went on vacation and when we came back it looked like this. Worked fine before leaving and on hotel WiFi last week. Have restarted my phone and his. Both are also up to date on iOS.
