Yeelight 1S Discoverable, but doesn't change colors with Local API

We have a decent percentage of users who are able to discover their new local bulbs, but they can’t change the colors of them. We aren’t sure what’s going on because about 70% of users have no issues. We made sure that the 30% who are having issues does indeed have Lan control on. Has anyone heard of this recently or know what the issue could be?

Users are still reporting issues with Yeelight 1S. We’ve tried LAN API with both set_scene and set_hsv. Are there any differences with the LAN Api for 1S vs the older bulbs?
