Hello @mike19, welcome back to the Fitbit community
Thank you for sharing your situation with us and letting us know about your inconvenience, it would be nice to help you out.
Taking into consideration that the notifications are not being sent to your Sense 2, I would like to mention that there is the possibility that they might be turned off. With this in mind, I'd suggest trying to perform the steps described below:
1. Unpair your Sense 2 from your Bluetooth settings.
2. Turn off your phone’s Bluetooth connection.
3. Force close the Fitbit app and restart your phone.
4. Restart your Sense 2 to refresh its performance.
5. Open the Fitbit app, tap your profile picture > Set up a Device.
6. Select your Sense 2 from the list, tap Replace Device, and follow the onscreen instructions.
Once this is completed, set up the notifications once more, make sure both DND and sleep mode are disabled and monitor your tracker’s behavior for the next few days.
