Why this matters:How to recognise this workaround on your side, and what closes it on your side — without telling you how to do the workaround.
How common it is: OS-driven MAC rotation is a documented platform default. Specific misconfiguration rate among parents is not established.
Detection
A device-pause or schedule that used to apply to the child’s device no longer applies after a recent OS update; the router’s client list shows a new randomised MAC for the device.
Fix (technical)
Re-bind the router’s MAC rule to the device’s current randomised address; better, move the schedule to the device-side Screen Time or Family Link so it no longer depends on the MAC at all. Do not rely on the router’s MAC list as the durable identity.
Fix (relational)
An OS update is the household’s chance to talk about what changed and why. Frame the re-binding as a check-up rather than as evidence the child did anything.
Residual risk
The rebound address will rotate again at the next non-persistent join or after the next OS release. Treat any router MAC rule as a maintenance item, not as a setting.
