I just responded about the extent of my experience in your other thread:
As I mentioned, I haven’t really looked at our verified the other models [yet], though I do have the original scale, scale X, and ultra scales, I haven’t verified if they support health connect yet, but I thought I saw in a support article that most of the scales were supposed to support health connect now or soon. If it’s not showing up in the settings for third party apps, we may need to pass that on to an employee with a link to the support article indicating they should now be supporting it on those models. I’d have to find that comparison chart that implied it should be supported now.
