I updated my firmware yesterday to version 1.5.7 and afterwards my decos will not maintain connectivity to the main deco.  Their LED will randomly flash red for a few seconds, then it will reconnect and turn green again.  This is not a new install and these devices were working without issue prior to the upgrade.

Things I have tried:
Rebooted all deco devices.  From the app, and by unplugging.
Removed and then added back the decos
Performed a reset using the button on the bottom of the deco

Any help/guidance is appreciated.
