Missing Activity achievements
My Apple Watch stopped reporting on my monthly challenges at the end of 2019. It shows that I have succeeded at my April 2020 challenge under the Go For It screen on my iPhone, for example, and it did the same for Jan, Feb, and March 2020, but under the Monthly Challenges screen, it stopped reporting anything after December 2019. It kept track of monthly challenges perfectly before that.
I have an Apple Watch 1. And an iPhone 6 Plus. (Really!) They are both updated as far as they can go. Any advice would be welcome!
