If you've correctly connected the accounts, you'll see, at minimum, "Fitbit Activity" with a 0 points value in your activity tracker at Weight Watchers. If you're not seeing this, you haven't synced the two accounts.
The way the sync works is that you don't earn the points when you do the activity, you earn the points when you exceed your normal level of activity. So a workout done in the morning won't show up until later in the day.
And sometimes it takes as long as 48 hours for the activity to sync.
A quick check -- manually enter the number o steps you've done into your Weight Watchers activity tracker to see if you've earned any points (you can delete the entry later).
If everything seems to be set up properly and your manual calculations show you should be earning points, chances are it's a problem with Weight Watchers, and you should talk to their technicians.
