I just pulled out the old original Apple Watch series (Series 0) and tried to connect it to my phone (iPhone XR on iOS 14). The pairing process starts, but it looks for an update and says that an update is needed. So when it tries to update, it says it is up to date (no update available).
I do not have an old phone to try an older iOS. Is there anything I can do? Most of my search has come up with nothing, but the one thing I found was trying an older phone on iOS 12. I just do not have that option.
