I have had some issues getting my Fitbit to work with Actifit. Today with the help of moderators on Acrifit's Discord channel we were able to get it figured out thr problem.
The problem was operator's error or at least forgetting how to operate the two apps together.
My activity has continued to stay above 10,000 for the past week or so. I can feel the positive effect of my increase of activity with yard work, greenhouse work, short hikes into woods, and lots of gardening. I have a lot of work to do in vegetable and flower garden from here forward.
