Hi there, @Nd7551. Welcome to the Fitbit Community Forums. I'm sorry to hear that you're having difficulties to set up notifications on your Versa 4. Thanks for taking the time to troubleshoot this issue before posting here. I'll be glad to help you with this!

To better assist you, may I know if when setting up your Versa 4 you were asked to set up notifications? Would you please guide me through all the steps you've done so far? 

In the meantime, please also confirm whether you've tried all the steps below:

• Make sure you’re using the latest version of the Fitbit app. For more information, see How do I use the Fitbit app?
• Make sure your Fitbit device is up-to-date. For more information, see How do I update my Fitbit device?
• Keep your phone nearby with the Fitbit app running in the background. Your phone should be within 30 feet (10 meters) of your watch.
• Call notifications must be turned on. For more information, see How do I get notifications from my phone on my Fitbit device?

If you continue to have issues, try the following troubleshooting steps:

1. On your phone, turn Bluetooth off and back on.
2. Restart your Fitbit device. For instructions, see How do I restart my Fitbit device?
3. Remove your Fitbit device's controls or calls from the list of Bluetooth devices on your phone.
4. Set up on-wrist calls again. For instructions, see How do I set up on-wrist calls on my Fitbit device?

Note that your Fitbit device's controls or calls might be listed as “Not Connected” in the list of Bluetooth devices on your phone. When you receive a phone call, the controls automatically reconnect. This feature requires more frequent charging.

Hope that helps!
