Cree Bulb "Unavailable" in ST App but Responds to Alexa

One of my 7 Cree Zigbee bulbs started showing offline in the ST app two days ago. However, it is responding to commands from webCoRE and Alexa. I have tried refreshing the device in the ST app a few times and once or twice it did come back “online” but it then returns to unavailable. I tried a bulb reset but so far I’ve not been able to get that to work. Any ideas? Contact ST Support on this one? It’s obviously still on the mesh as it is responding to Alexa and webCoRE. EDIT: I’m going to go ahead and report to ST Support.
