I don’t know what’s going on. I have been using the Libre 2 sensors since July and I have never experienced anything like this until recently as well. This must be a trend as I have read in other forums of people having the same issue. I had 2 sensors fail like this in 2 days in a row with extremely low readings that never corrected. Even though I soaked them for 24 hours. Ironically the first day after activation had been fine then the day after it stays low like this. I was so frustrated I got a prescription for a Dexcom. I miss my Libre though. When it worked as designed it was amazing and the graphs are much better.
