I really wish Samsung would fix the new app. I have two Cree bulbs (Zigbee) and two ST outlets that often show as “disconnected” in the new app but show as “on-line” in the Groovy IDE and work fine with the Classic app, IFTTT and Alexa. Rebooting the Hub v2 does not resolve the issue and deleting the devices and rediscovering them is a royal pain in the a**! (especially since they are used in routines and IFTTT applets)
NOTE: Secure Mode is turned off, so they should reconnect automatically
I have nine Z-Wave dimmers, outlets and sensors that never have a problem.
Does Samsung monitor this forum to be informed about issues/bugs?
EDIT: I sent an email to Samsung support and referenced this thread.
