should I use 2 apple ids to manage from my iMac for an iPad my grandchildren use? I have Apple One Subscription with arcade and music but I do not want them to have access to my photos, files and other things I use and backup to iCloud. Or do I set up iPad separately with an Apple ID and simply loose benefits of my subscription?
