I'm new to Apple as of the iPhone 7 Plus and just bought an iPad Pro to go with it. I seem to be having some issues with iMessage syncing between them. The main thing is when I delete a thread from one device, it doesn't get deleted from the other. Is that normal? It also seems to disconnect every once in a while from my iPad. Calls and texts will randomly stop showing on my iPad. Is there any known reason for this happening?
