Screentime

Hello VAR and welcome to Apple Support Communities,

If we understand your post correctly, you'd like to set up separate Screen Time limits on multiple devices using the same Apple ID. We’d like to help.

You can use these steps to turn on or off the option to share Screen Time limits across your devices.

Use Screen Time on all your devices

To share your Screen Time settings and reports across all your devices, make sure you’re signed in with the same Apple ID on each device and Share Across Devices is turned on.

1. Go to Settings  > Screen Time.

2. Scroll down, then turn on Share Across Devices.

See the full article here: Keep track of your screen time on iPhone - Apple Support

Let us know if that resolves this issue for you.

Thanks for using the Apple Support Communities.
