Wyze ultra scale is ultra unreliable

I’ve been using this scale for the last six months and the reproducibility of measurements is +/- 2 pounds at best, If you take multiple measurements you’re gonna get multiple results, Which can vary by as much 2 pounds.

Something has also changed, with The scale no longer talking to my bluetooth phone app without the phone first being turned on. Not sure what has changed, but I used to be able to have the scale transmit to my phone previous measurements. But now the phone has to always be turned on f.or me to receive the bluetooth data period

Has anyone else had this issue?
