I understand how crucial your Apple Pencil is for your artistic work. Since you've already tried several troubleshooting steps, and the issue persists, here are a few more things you can try:
1. **Check iPad Compatibility:** Ensure that your 6th generation iPad is indeed compatible with the Apple Pencil. The 6th gen iPad should work with the first-generation Apple Pencil.
2. **Check Bluetooth Settings:** Double-check that Bluetooth is turned on both on your iPad and the Apple Pencil. Sometimes, a simple toggle of Bluetooth may help.
3. **Clean the Connector:** Examine the Lightning connector on your Apple Pencil and the Lightning port on your iPad. Make sure they are clean and free from debris or dirt. Use a soft, lint-free cloth or an electronics cleaning brush to gently clean them.
4. **Reset Network Settings:** In some cases, resetting your network settings on your iPad might help. Go to "Settings" > "General" > "Reset" > "Reset Network Settings." This won't erase your data but will reset Wi-Fi and Bluetooth settings.
5. **Update iPad Software:** Ensure that your iPad has the latest iOS version installed. If not, update your iPad to the latest software as sometimes issues can be resolved through software updates.
6. **Try on Another iPad:** If possible, try using your Apple Pencil on another compatible iPad to see if it works there. This can help determine if the issue is with the Pencil or the iPad.
7. **Apple Support:** If none of these steps resolve the problem, it's advisable to contact Apple Support or visit an Apple Store for further assistance. There may be an underlying hardware issue with either your Apple Pencil or your iPad that needs professional attention.
Given your reliance on the Apple Pencil for your artwork, I recommend reaching out to Apple Support as soon as possible to get this issue resolved efficiently.
