I have the iPhone 11.... and I just bought a Nike series 5, 40mm watch from Best Buy this Black Friday, so like a week ago. So when I opened the watch it had to be updated before I could connect to my phone. But I couldn’t get them to pair ! on my phone it kept saying I wasn’t connected to the internet! Even though I Was connected 100%... so I went on YouTube to try and find some helpful tips and what I found was, Go to settings and reset network settings, Then after That I shut down my phone and left it off for like 30 seconds. And after all that it still kept saying not connected to internet. Lol So I was sooo angry! That I just gave up and Left both my phone and my watch Charging over night. And when I woke up in the morning I tried it again and It WORKED! I was so happy. Then I realized your watch and phone both have to be 100% charged and Keep them hooked on the charger or else the new Update for ur watch Won’t show up on your phone because it’s usually like A 40-60 minute long update... so let them both be 100% plus hooked on charger and it will work. I wasted all that time resetting my phone when all I had to do was be 100% charged lol
