Openhab 3.2 VolumeStep for Speaker not working

This is because the change for this one was introduced after OH 3.2 release and won’t be reflected until 3.3 is released or if you switch to the snapshot version once the Main UI changes are merged.

@Matte_Goghero You are on the right track. Could you please provide the details of the item and the Alexa metadata you tried to configure?
