I have an Apple Watch problem. I'm obsessed. I can't not close my rings. Every challenge, accepted.
So the March Challenge is 31 workouts - no problem. I double up a couple days just to be sure.
Then it's the 26th and I look at my progress - wait, 13? It's not counting all my workouts!!
But when I look at the Workouts tab on the iPhone Activity app, sure enough, they're all there.
Googled around, nothing jumped out at me, so I started a chat with Apple.
To make a long story short, they had me unpair and re-pair my watch and my phone, which was kind of time consuming but not a big deal.
And the problem was fixed! March Challenge completed!!
Now if this happens to you - even if you just have to unpair/re-pair your watch and phone for any reason - here are some things to keep in mind:
1. by the end of the day, my watch battery was super low. if you're going to unpair/re-pair, you might want to put it on the charger while you do so.
2. I got to the grocery store to discover that my credit cards weren't there anymore. you have to go into the Watch app on iPhone and re-add your cards, which is just a couple of clicks, BUT you do have to know your cards' PIN codes.
