Dexcom G6 follower app not updating

Followers get readings from the Dexcom cloud server, so the wearer's phone must be online and the G6 app must keep running. School Wi-Fi firewalls can block it. (Dexcom)

What the maker says to do

1. Make sure the wearer's phone has a stable data plan or Wi-Fi connection.
2. On a school network, ask the school IT department to allow the Dexcom Follow connection.
3. Ask the wearer to keep the G6 app running and not close it.
4. Check status.dexcom.com for a Dexcom server problem.

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.
