I’ve one custom smartapp that has been working ok during months. Today 2018/Feb/18 it is out of order. A second smartapp also presents same issues at same time.
Individual devices seems ok, it is possible to connect and use them from mobile app. Moreover, its events are logged in the monitor window of the mobile app.
The app fails even when using the simulator with the real hub but virtual devices: it is installed/updated, but events from devices (physical or virtual) are not received nor log messages from the callbacks appears.
Everything is ok in the virtual location / virtual hub.
Is smartthings having a global problem (UK area) ?
