Hi @Bosse , it seems the iPad is running the App Store version of the app which does not have support for syncing.
For sync to work, each device should have the Sync Testflight build installed, should be using the same Apple account and logged-in inside the Clear app.
The original post has the steps for the installation. I would recommend taking a backup on both the iPhone and the iPad before installing the Sync Testflight build on the iPad.
