Mine are working however some (not all) of my Hue bulbs are going offline and online repeatedly in the ST app. Again, this is post the ST hub FW update yesterday.
UPDATE: Appears to be Device Health related. But definitely started right after ST hub FW update yesterday.
I don’t think I have seen this before in Live Logging for my Hue bridge:
9:55:21 AM: error java.lang.NumberFormatException: For input string: "2." @line 701 (getHost)
For reference I have opened a ticket with Support - ticket #759326.
