Hi Everybody. I am not a frequent (ever?) poster but...as an extremely heavy user of screen time, and for a long time, and for 4 children who are about to age out - I know how frustrating screen time can be. This issue has vexed me for a very long time...years and over multiple accounts.
It's frustrating because the "app limits" become useless as you never really know which one is turned on, which one was deleted, etc. (don't even get me started on the new approval system for screen time requests...). I LOVE that Apple installed screen time but it is just falling short of Apple's standards right now. Best example: the fact that screen time stops working when a device needs updating. Ummm, what? Do you know how many times, over the years, my children have resisted an update because they know this? I can only imagine there is a problem with syncing, over multiple devices, over multiple accounts, interconnected with a family account, and with additional restrictions because it is a "child" account.
So, I felt I had to write at 10 pm on a Tuesday so if you are frustrated by this problem and want a solution that worked tonight for a guy who thought he tried everything over the last 3 years - to no avail - I've got one.
I know others have posted they tried this but, since it worked for me, you could still give it a shot. Here is what I did:
1) Signed out of Apple on all devices on my child's account.
2) Went to my child's apple account on alternative device and deleted all devices from my child's account.
3) Reset Network Settings on my child's devices.
3) Disinvited my account from our "family sharing" account (managed by my spouse).
4) Invited my child to my individual account's "family sharing". (If the child is under 13, this is the only way to remove them from the initial account's "family sharing" - by inviting them to another adult's "family sharing". See here for instructions).
5) Signed back in to Apple on my child's device.
All of the suddenly disappearing app limits, or suddenly reappearing app limits, are eliminated. To be clear, I believe the act of removing my child's account from the family account, as well as the reassigning to another adult's account, is the reason for the fix - but I am not 100% sure.
My next step is to invite my child back into the main family account (managed by my spouse) and see if the app limit issue continues to be fixed. Fingers crossed.
Hope this helps. If you have questions about the process, I'll try to answer.
