Good morning folks, I am using the Freestyle 2 , 9 days in first ever sensor it quit on me, phoned Abbott they are sending a replacement (5/7 days), my chemist told me on the phone my first repeat of 2 sensors would be in Friday mid afternoon, after loads of error messages I pulled the sensor off, and went to the chemist when I got there they gave me ketone strips and 1 freestyle one sensor saying there are issues getting sensors for the Freestyle 2, I was using the app on an android phone, if I place this sensor (freestyle1) on my arm will the app be good to go, I`m a bit confused.
