Medtronic Simplera follower app not updating

CareLink Connect only updates when both phones are online, the wearer's app has Sync to CareLink on and is logged in to CareLink Personal, and the wearer's phone is near the device. The Home screen shows when data was last uploaded. (Medtronic; Medtronic user guide, p. 2; Medtronic user guide, p. 48)

What the maker says to do

1. Make sure the follower's phone is online and logged in to CareLink Connect.
2. Ask the wearer to check that their phone is online and within about 20 feet of the pump or sensor.
3. Ask the wearer to turn on Sync to CareLink and stay logged in to CareLink Personal.
4. When you open the app, allow at least 20 seconds for data to refresh.

Simplera (standalone) sends readings to the Simplera app on a phone; Simplera Sync pairs with the MiniMed 780G pump, and the MiniMed Mobile app is a secondary display for the pump.
