Dexcom ONE+ follower app not updating

The Follow app can be behind the wearer's ONE+ app. A dash (---) next to an active sharer means the follower should ask the wearer to check their app; Disconnected means the wearer turned Share off. (Dexcom user guide, p. 49; Dexcom user guide, p. 19)

What the maker says to do

1. Ask the wearer to open the Dexcom ONE+ app and check it.
2. Check that the wearer has Share turned on.
3. Make sure both phones have a steady internet connection.

Dexcom ONE+ is not sold in the US. All facts here come from Dexcom's UK and Ireland pages, the UK App Store listing and the outside-US English user guide (mmol/L). Dexcom says Share and Follow may not be available in all regions.

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.
