Clicking a device does nothing 1.6.67

I’ve been running smart things with the same devices on the same Wi-Fi network for years without a problem.

After upgrading to iOS 1.6.67 my devices all seen grey in colour and when I click them nothing happens. Apart from that everything else seems to work.

Does anybody know what the problem is here?

Most people who’ve been having issues after the upgrade on iOS who have had issues seem to be able to clear it by uninstalling the app and then reinstalling. Have you tried this yet?


Thank you. That fixed it.
