Dexcom G7 follower not getting alerts

A follower gets no notifications if they are turned off in the Follow app or in phone settings, if a delay is set, or if the sharer's status is No Data, Disconnected, Not Sharing or Removed. (Dexcom)

What the maker says to do

1. In Dexcom Follow, turn on the notifications you want for each sharer.
2. Check each notification's delay setting.
3. Check the sharer's status and contact the sharer if it is not active.
4. Turn on notifications for Dexcom Follow in the phone settings.
5. Do not use Do Not Disturb, Focus or Scheduled Summary for Follow, or add Follow as an allowed 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.
