Hello @Alexmihai24 and @MBBlaze, thanks for joining us, it's great to have you on board. It's nice to see you too @SunsetRunner, thanks for your help. 
@Alexmihai24 and @MBBlaze, please check the link @SunsetRunner kindly provided and try the troubleshooting steps listed there. If that doesn't seem to work, my suggestion would be setting up your tracker as a new device. Don't worry, the information already stored in your account won't get deleted.
To set up your tracker as a new device:
- Open the Fitbit app and tap on the Account tab at the bottom of the screen, then tap on "Set up a New Device"
- Choose your tracker and follow the onscreen instructions to continue
- When the app asks you to replace your current tracker, please replace it and continue with the process.
I hope this can be helpful, give it a try and keep me posted in case you need anything else!
