Currently my spouse is getting sensor readings that are roughly a difference of 100 compared to a finger stick, is there an issue with his freestyle libre 2 sensor? He just got out of the hospital with DKA and he uses a Tandem pump along with the libre 2. Also, he has a newer phone (Samsung Z flip3), when will these apps be compatible??? He had a Dexcom and the only reason he switched is because his insurance wouldn't cover the Dexcom unit....we are not liking the freestyle so far!
