FreeStyle Libre 3 and 3 Plus follower app not updating
LibreLinkUp shows No Recent Data when it has had no reading for 5 minutes. For Libre 3 the causes are no internet on the wearer's phone, no active sensor, signal loss, or a LibreView outage. (Abbott; App Store listing)
What the maker says to do
- Make sure the wearer's phone has an internet connection.
- Make sure the wearer's app is not force closed.
- Check that the wearer has an active sensor and is not in signal loss.
- Make sure the follower's phone is online and not in Airplane Mode.
In the US, Abbott's Libre app replaces the FreeStyle Libre 3 app, whose App Store listing says it is not the latest app.
A call when readings stop
Glide sends every phone on the profile a lost signal banner after 30 minutes without a reading, and overnight it can call a phone number you verify (Premium). How the lost-signal call works.
