Help. Alexa can only turn on and off lights. No dimming

Has anyone gotten their Alexa to dim lights?
I’ve tried a couple different things.

Downloaded the skill to Alexa.
Setup everything I think right.
I ask Alexa to turn on/off family room light and it works.
I ask Alexa to turn on/off the back light and it works.
I have a group setup of all lights. Ask her to turn on/off and it works.
I ask her to dim the family room light to 50%, and Alexa says “hrm family room, not responding”
I ask her to dim back light to 50%, and Alexa says “him back light not responding”

I tried deleting all lights, groups and starting from scratch.

Still same response.

Try a simple name

Looks like the firmware update worked first. But I also change the names.
