Apple Pencil has stopped working in apps?

Hello! I just charged my Apple Pencil up and it works for basic tapping + dragging / writing in notes / scribble, but it suddenly stopped working in apps such as Goodnotes (I am able to write, however it does not sense pressure sensitivity) + Procreate. It was working perfectly fine before it died so I have no idea what the issue is. I have already tried hard resetting my device (iPad Pro 12.9, 4th gen) as well as reconnecting it in bluetooth. Downloading the apps again does not seem to work either. I’m not sure what else to do. I’ve been holding off on downloading iOS 14.6, but my iPad seemed to have downloaded it by itself when I left my Pencil to charge so maybe that was the cause.. has anyone else had the same problem?
