Yes. The target glucose limit will sync between your t:connect mobile app and web application to give you the same calculation of time in range regardless of which application you are viewing.
If you customize this range, there is sometimes a short delay in updating both systems to match. (i.e. if you update the setting in your mobile app, you may need to wait up to an hour to see that change reflected in your t:connect web application.)
For Dexcom continuous glucose monitoring (CGM) specific issues including calibration prompt will not clear, sensor failure during the 2-hour warmup, “no restarts” alert or physical problems with your sensor or transmitter, such as bleeding, bruising, skin reaction, adhesive issues, applicator issues, or broken wires, please contact Dexcom using one of the options at dexcom.com/contact or report the issue online at https://dexcom.custhelp.com/app/webform.
Please see table for a full list of who to contact for Dexcom CGM issues.
Tandem handles issues such as loss of connection (on pump only) and the invalid transmitter (Alert 29) on pump only.
