Hello @Simdigity, have a warm welcome, it's great to have you on board the Community! 

Have you tried restarting your Blaze by pressing and holding the Back and Select buttons (left and bottom right) until you see the Fitbit logo on the screen? If so, please restart your mobile device as well, plug in your Blaze and make sure it's charging and try to set it up once again:

1. Open the Fitbit app and tap on the Account tab at the bottom of the screen, then tap on "Set up a New Device"
2. Choose your tracker and follow the onscreen instructions to continue

If that doesn't do the trick, my best recommendation would be contacting our Support Team. Let them know the steps you've performed so far, I'm sure they will be able to get you back on track! 

Please give it a try and let me know the outcome.
