New Apple Pencil pro isn’t working.

Troubleshooting while travelling is often difficult and/or frustrating - as you likely have limited access to support options. Fortunately, your iPad should remain useable without its Pencil - as you can replicate (albeit less precise) Pencil interaction with your finger until the problem is resolved with your Pencil.

Clearly, without more information, contributors here have no idea what you may have already tried with assistance from Apple Support. It is perhaps unlikely that we can provide any more insight into your current difficulties than you have already obtained directly from Apple.

Nonetheless, in absence of information as to what you have already attempted, begin by "forgetting" the Pencil from Bluetooth settings:

Settings > Bluetooth > [My Devices] Apple Pencil - tap the blue "i" icon, then select Forget this Device

Once removed from Bluetooth Settings, re-pair the Pencil with the iPad.

If this doesn't resolve the problem, the next step is to reset your iPad's Network Settings:

Settings > General > Transfer or Reset iPad > Reset > Reset Network Settings

The iPad User Guide provides guidance for pairing and charging your Pencil Pro with your iPad:

If you are experiencing inconsistencies with your Apple Pencil and iPad, you would be best advised to seek assistance directly from Apple Support. You can contact the Support Team using the Support link at top-right or bottom-left of this page.

Alternatively you can initiate and manage your support cases using the excellent Apple Support App. If not already installed on your iPad, the App can be downloaded from the App Store:
