Apple Watch pairing
i have just purchased a series 5 Apple Watch (demo model) to replace my old one. When I try to pair it and set it up in the app it says it needs to have the new update and only gives me the choice to update before I pair it. I then click search for update but it seems to load for ages with no luck for the update to show up and will either say I have no wifi (when I do) or just keep loading. Anyone have the same problem and know how to fix it? Thanks in advance:)
