My pencil seems to be broken. It keeps disconnecting from my iPP after just 1-2 minutes of active use. Attaching the pencil to the iPP immediately restores the connection - for another 1-2 minutes. Is there anything else I can do before taking the trip to the Apple store? Re-pairing didn’t help. The tip is rather new and clean. My Airpods stay connected so I don’t believe the iPP is causing this.
