SmartThings iOS app is suddenly not working. All devices showing "grey out"

What most people is experiencing here, is the same I started noticing few days ago. Nothing can be controlled or edited on Favorites and now even worst, all devices shows like them (greyed out status), but only on all my iOS app.
