Yesterday I updated my iPhone 6 to iOS 10.0.1. Several of my apps, like Pedometer++, Swarm, and Yelp, support iMessage, but instead of showing content I can share, they just show an icon. See the Pedometer++ screenshot below. Swarm, Yelp, etc., appear similarly.
The built-in #images and Music iMessage apps work correctly, as do simple sticker packs.
I've tried power-cycling my phone with no effect. I've also tried disabling and re-enabling the apps in "Manage" with no effect. Does anyone know what causes this behavior?
