Does not allow Select "Fitbit" device during setup

I have played before with using my fitbit to tracks teps with no problem. I set up a new game a couple months go, but it would not let me choose “Fitbit” undert the select device section during setup. I selected “Phone” and it did let me move forward and tracked my steps from my phone data.

I click “Fitbit” and it shows a checkmark (See photo), but then nothing happens when I press “Next.” I’ve tried hitting the "Next’ button dozens of times and nothing happens if “Fitbit” is selected.

I deleted my previous game, waited a few weeks, and tried again, but it will not connect. Using phone steps is not motivating for me. How can I connect to my fitbit?
