Given that you’ve already adjusted pressure settings inside Procreate and confirmed the app supports it, it’s likely that the issue lies either with the Pencil hardware itself or with how it's pairing to the iPad.
Let’s start with compatibility. The iPad 10th generation actually does not natively support the 1st-gen Apple Pencil without an adapter. Apple did something odd here: the 10th-gen iPad uses a USB-C port, while the 1st-gen Pencil uses Lightning, and Apple’s workaround was to sell a USB-C to Apple Pencil Adapter to allow pairing and charging. Ok, with that said, if you're not using this official adapter, or if it didn't pair properly during initial setup, that could cause partial functionality—like touch input working but pressure not registering.
Assuming that you are:
- Make sure that the Pencil is fully charged (via the adapter, not just a cable).
- The Pencil is fully paired via Settings > Bluetooth. If it's already paired, try unpairing and re-pairing it.
- Restart your iPad after pairing.
If all that checks out, test pressure sensitivity in the Notes app (draw with varying pressure). If it still doesn’t respond there, it’s likely a hardware issue—either with the Pencil's pressure sensors or a firmware quirk. In that case, try resetting the Pencil by forgetting it from Bluetooth, rebooting your iPad, and re-pairing. If still no luck, it may be time for an Apple Support chat or visit.
