I’m using Libre 2, no pump. I’m using Libre Linkup in my android phone, connecting the CGM Connect widget. Linkup needs a password setting in it, as does the widget.
This seems to be the problem as somehow the passwords on Libre Link, Linkup and the widget had got out of sync yesterday while I was in the gym. After resetting the password for all 3 apps 11 times I’ve finally got them all talking to eachother at last and it’s all now working again.
I hadn’t realised just how much I relied on it being so easily available on my watch these days until it wasn’t.
Thanks @DickBarton for coming back, though.
