Jaylee, some downside to expect then! That is a pain, will see how it goes next week. Another minor annoyance: with Libre 1 I use both a librelink & meter, ( meter is only 'just in case' but still gets a few swipes each sensor)... that's as long as you scan with meter first time, then the mobile on starting each sensor. Libre 2 doesn't offer this as you only have option to get alarms on the first device you sync sensor with, so once connected to a phone you can't activate or use a meter. (although they did say to try and see what happens).
