So, I've discovered I can't use the app on my phone because my Sensor is already connected to the Reader. So for another 10 days I can't share my information with my doctor unless I continue to finger prick and run parrallel numbers on my Contour Next One Glucose meter - that I can email reports from. So I can carry either the Libre 2 Reader and not share OR carry the phone and have no carry and additional blood glucose meter for emergencies. This is not convenient.
