Abbott is the best company to deal with at Christmas I had 2 sensors fail. Called Abbott they talked me through the issues then decided both were malfunction sent me out 2 to replace them they arrived in less then a week
I had this issue this morning thought I would try settings went into connection hit onto nfc to shut it off count to 10 turned it back on tried to scan again it worked
IF YOU FIND IT WILL NOT READ GO INTO YOUR SETTINGS HIT ONTO CONNECTIONS HIT ONTO THE NFC TO SHUT IT OFF COUNT TO 10 TURN IT BACK ON IT SHOULD READ THEN
