Hi I've had been using freestyle libre for about 2 yrs, just got version 2 which has the alarm system for high and low blood glucose. My first sensor was fine, changed it on Monday as per the end of 14 days and since then (it is connected to my samsung phone) it continues to say the alarm is unable to work as some notification or permission has not been authorised. I have spent the past 2 days checking every notification and permission, changed the sensor last night for another (still saying it cant work) even been to a phone shop to buy a new phone but was assured the senor is compatible Samsung J6. MY partner who teachers tech at university level is pulling his hair out, he said the blue tooth wasn't connected but the more he looks into this the more frustrated he is becoming. I have spoken to Abbot who have offered a replacement sensor but the problem is still there, constant reminders on my phone telling me the alarm cant work as permission is not given. Anyone using libre 2 with success ?
