What causes existing apps on Apple Watch to not have icons anymore? The app is still on the watch, but the art for the app is gone. Had this happen about five times in the last week.
No idea. This was a huge issue, for me at least on my iPhone when I searched stuff in iOS 8. Icons wouldn't load. I saw Twitter had that icon on my watch this last week, so I just uninstalled it then reinstalled that app. It took forever so I had to restart my watch.... But idk why this is an issue.
