Facebook and Twitter icons

[Fireball Dragon]

When I receive notifications on my Apple Watch from either Facebook or Twitter, I’m not seeing the relevant icon.

There is just a blank tile above the notification, and not the icon of the relevant app.

Any advice on how to fix this or why this is happening?

I'm experiencing this same issue with Twitter and Snapchat. It seems as though it's an issue on the developer's side, not Apple's.
