My body battery went below 5% one day in early March and now no longer goes up very much, if at all, even after 9/10 hours sleep. My stress readings are also permanently high even when asleep which was never the case until the body battery crashed. I have reset the watch / app several times. The body battery then jumps up but shortly crashes back to 0 again. The readings used to go up and down as expected and now pretty much flatline unless I reset the watch. I have attached pictures of what the readings looked like before and what they look like now.
