DTEK50 - syncing with Fitbit Blaze?

How do you sync the DTEK50 with a Fitbit Blaze? When I try to connect via Bluetooth, it states "rejected by Blaze" on my phone. Solution?

If your tracker still won't sync, try these steps:

Force quit and then reopen the Fitbit app.
If the tracker doesn't sync, quit the app again and try turning Bluetooth off and on.
Reopen the app once more. If the tracker doesn't sync, try again after rebooting your mobile device.
If your tracker doesn't sync, try again after restarting your tracker. For instructions see How do I restart my tracker?
Lastly, try uninstalling and reinstalling the Fitbit app

My fitbit had to be rebooted after the Christmas holidays. My Flex 2 model had to be placed in the charger and then I had to press the button on the charger 3 times in 5 seconds. Check the fitbit support site on how to reboot yours.
