Anybody else having issues with alarms not working properly with an iPhone? I keep getting a message telling me “alarms are only available when you start a FS Libre2 sensor with this device” - how else did it think I started the device?? Alarms are set , notifications are on, but sometimes the alarm for a low or high goes off…and sometimes it doesn’t. Also, iPhone can be sitting right beside me and the Signal Loss Alarm will go off…doesn’t make sense. Anybody??
