How to "update" to an older version?

[Nuke21]

It isn't a secret that with every update the charge 6 gets worse and worse. With the latest "update" the watch no longer remains connected to smart treadmills and i imagine any other machine. As soon as the watch screen goes out, even with "always on" display on, it will disconnect. So this is approximately after ten seconds. How do we get ahold of the engineers to go back to an older "working" version of this watch?
