Update devices using iCloud for screen time?
I was trying to set Downtime on my son’s iPad through Family settings but got a pop-up error message saying I need to update his devices “using iCloud for screen time” and that Downtown would not apply until his device software has been updated (see attached screenshot). This seems to imply that I should be able to update his iPad software from my device (iPhone) but I cannot find where/how to do this. Can anyone shed light on how?
