Hi everyone. I recently switched from Dexcom to Libre and have literally had nothing but problems.; it seems to always be inaccurate for me (whereas Dexcom was consistently amazing on the accuracy front). Anyway, my latest issue is that I inserted a sensor last night and it was perfect for the first few hours and also was fine when I woke up. However, for the last 5 hours it has just been reading "LO" and numbers like 2.7, 2.3, 2.9 even though my finger pricks are between 6 and 8. Any chance this sensor may "fix itself" -- should I give it a bit longer? Or best to just take it off, call customer services (again...) and start a new one? Annoying I can't calibrate it. Thanks so much.
