I'm sorry you're having those issues. CGMs can have their problems. My doctor said false low readings is a common problem reported with both Dexcom and Freestyle Libre.
I have problems with my Freestyle Libre giving me false low readings but only on my left arm intermittently. I wasted 2 sensors figuring out the problem when I was getting obviously constant false low readings. Between Abbot my doctor and my own experimenting it was determined after I had experienced an extreme weight loss the subcutaneous tissue in that area of my arm had thinned out too much for the sensor to work reliably. I have since only installed sensors on my right arm even though I've regained the weight and more. I now have a fear of wasting expensive sensors. Because of my experimenting I had to purchase extra sensors online for about $100 a piece. That's my copay for 6-7 sensors depending on which month the is fulfilled.

@Justmeraeagain I studied them both since I received mine 2 years ago. They both have their pros and cons. Yours is supposedly more accurate than mine but equal to the Libre 3. I only use the reader not my phone. But unlike yours keeping contact with your phone the reader has to be held close to the sensor. Yet now and then it gives a message contact lost scan sensor which makes no sense. I never take the reader out of the house when I leave. And that message never greats me. It certainly has nothing to do with being near the sensor when it's not being used. Oh lifes mysteries. I'm too lazy to investigate this one because it's easy to resolve.

@Justmeraeagain Yup. After dealing with it long enough we develop a sense of where we are just by the way we feel.
