Can’t pair
So I have a series 3 watch that has been sitting in a draw for about three years now, I bought the new Iphone 11 and I reset the watch to the factory default and now I’m trying to pair it to my phone and it just not happening. At first they established a connection and then it tells me the update is required and I click on it then the connection fails. I did all the rebooting now what do I do ?
