While you may be using a new/different Apple Account (formerly known as an AppleID) with your new iPad, are you signed-in to any other Apple services (e.g. the App Store) using your original Apple Account credentials? If yes, this may account for unexpected behaviour - such as with FindMy.
Some Users, like you, choose to use different Apple Accounts for different devices. However, due to other practicalities (such as retaining access to all the paid Apps that were purchased using a different Account) will sign-in the Apple Store and other Apple services to maintain continuity of their activities. In such circumstances, while the iPad may appear to be signed-in using a different Apple Account, you are in fact signed-in using multiple Apple Accounts. While this practice can be an effective method by which to use Apple devices, you can encounter unexpected behaviours.
If you are certain that you are signed-in to the iPad and all other Apple Services using just the new Apple Account, then something else is occurring...
First, ensure that the iPad has been updated to the most recent version of iPadOS. At the time of writing, iPadOS 26.7 is current - and for devices that support it, an upgrade to iPadOS 27 is optionally available.
If your iPad is not operating as expected, try a forced-restart - as this will often clear an isolated or post-update software issue:
Force restart iPad (models with Face ID or with Touch ID in the top button)
If your iPad doesn’t have the Home button, do the following:
- Press and quickly release the volume button nearest to the top button.
- Press and quickly release the volume button farthest from the top button.
- Press and hold the top button.
- When the Apple logo appears, release the top button.

If the problem persists after performing the restart, it may be necessary to reset your iPad settings. While this reset will not cause any loss of data, as a precaution, it is always wise to ensure that you have a current iCloud or iTunes backup before performing the reset:

When you are happy to proceed, you can perform the reset from iPad settings:
Settings > General > Transfer or Reset iPad > Reset > Reset All Settings
If the problem still doesn’t clear, the next step is to reset the iPad to factory settings:
