Yerterday I tried resetting the hole thing, the hub.
Uninstalled the smartthings app and deletes everything from the page https://graph-na02-useast1.api.smartthings.com/login/auth
Just now I tried installing the blink handlers and app again (step buy step form this blog) and when i go to install the app on the smartthings app still apears the 5.0.7 version. These is veryyyy extrange. I double checked and the code is the version 5.0.9
