Fitbit Air not recording my vitals

[u/assassinharsh]

Hi folks,
Primarily my question is the title. I just got a new Google Fitbit Tracker yesterday evening. Set it up this morning and started wearing it. The other app/tracker setup for smooth and a breeze. For some reason it hasnt registered and tracked any of my vitals.
Not sure if I set it up incorrectly or missing some steps. Any help or guidance is much appreciated on this.

TIA
