Customization in the Galaxy Wearable app

The Galaxy Wearable app may experience watch face editor loading issues with complex watch faces that offer extensive customization options. This is a known issue and can sometimes be prevented by clearing the Galaxy Wearable app cache and performing a force-stop. We're currently waiting for a resultion from Samsung.

Note that this is not watch faces fault. Customization directly on watch should be working correctly.
