"Apple notes error: can't share notes with my sisters on my phone. It gives the message that the note is unavailable. The owner stop sharing, or you don't have permission to open it. I have checked all my settings and preferences and can't find it anywhere that I might have blocked sharing. They can see the list but I can’t why?"
