Scale not trying to do body measurements; not sending data to app

Over the last few days, my scale has stopped trying to do body fat measurements. I step on the scale, it shows me my weight, blinks and shows me my weight again. It doesn’t do the - - - … trying to do the additional measurement. In addition, while the app connects to the scale, it’s not receiving any data.

Any idea why this is happening and how I fix it? One thought I had is that it suddenly thinks I’m a guest user but I can’t find any docs on how guest user mode works. If this is the case, how do I get it to realize I’m me?
