Lights no longer working with Alexa

I’ve got 4 bulbs in my living room and 2 of them are no longer working with Alexa, they had for months with no issues till recently. They show up as discovered in the smartthings Alexa skill, but Alexa doesn’t show up as a smartapp for just those two devices in smartthings.

I’ve tried forgetting the devices and re-adding to smartthings and Alexa and it’s the same result. Not sure if the next steps I should try.

I am experiencing the same thing. I just re did my hub as i had to do a reset due to a known z-wave issue. It does not see ANY of my devices upon with a discovery.
