Thank you for the information provided.

Please restart your Fitbit Charge 3 by following these instructions. Whether this doesn't help, you can perform a long restart:

1. Connect the device to the charging cable. 
2. While the device is plugged into the charging cable, press and hold the button down for 15 seconds. 
3. The device turns on and shows a battery icon. Two vibrations occur: first a short vibration, then a medium vibration. 
4. The device turns off.
5. The device turns on and shows a progress bar and short vibrations occur. The progress bar completes. Note: A total of 7 short vibrations occur. 
6. Remove the device from the charging cable. The device shuts down.
7. Important: Plug the device into the charging cable again.

Hope this helps.

Mine did the same on 5/31/21 except it gave me the three lines and shutdown. I wiped the sensor and placed it on the charger. It wasn’t until yesterday that I noticed the HR monitor stopped working. The signals no longer appear. I have a video of the screen flips. Please advise.
