I’m having the same issue with my daughter’s pencil. We have several 11 inch iPad Pros in the family. When we connect the pencil to the side of any iPad, the iPads recognize the pencil and can see the status of it’s charge. However, once connected none of the iPads are responding to the pencil in the OS, in Procreate, or in any browser. I know it isn’t a problem with the iPads, because all of the other pencils can be rotated and function with no issues. So it’s definitely an issue with the pencil. We replaced the nib with no luck. I performed a visual comparison between a working 2nd gen Apple Pencil and the subject problem pencil. Nothing stands out as a possible root cause. There are no cracks on the case and all of the conductive material on the tip (under the nib) appears to be intact, including the conductive square on the top. I wish I knew more about the construction of the pencil itself, as I feel this would help me identify root cause. I’ll post again if I can figure anything out.
