Lily body battery stuck at 5%

Hello, I've had my Lily for just over a month now and it seems like the body battery is constantly stuck at 5% and stress levels are showing very high, even when I'm just sitting and relaxing. There's been 3 times that it actually went up to about 10-15% while wearing it and then quickly drained again. I have noticed when I'm not wearing the watch to charge it or take a shower or if I forget over night, upon putting it back on, my body battery percentage increases. Once after not wearing it for 4 hour, my percentage went up to 53%, but within a few hours, it quickly drained again. I have an old Vivomove style that still works and it shows what seems to be a more accurate reading of my body battery percentage and stress levels. I've already tried resetting the Lily, but it quickly went back to displaying the same low BB levels and high stress levels. Is there anything I can do to fix this? Thank you!
