My scale has been working fine for a long time. I have been using it several times a day right now due to needing to monitor water retention related to a heart issue. It worked fine for the first 3 times this morning and then the next time I stepped on it, it started showing random weights/numbers that were not even close to mine and were changing rapidly.
I thought it might be start of low battery, so I charged it. This did not fix it. When I set the scale on the floor, it immediately displayed 396.8 and stayed on (nobody was on the scale) for a while, then shut off. I tried stepping on it, it gave that same weight and then started fluctuating in the 100s. It might be throwing random numbers. The balancing arrows on the edges just kept moving around. I got off the scale and it continued to displayed the random numbers. It eventually turned off after staying on about 2 minutes. Each time I try to stand on it, it now does this same thing.
