Fitbit Blaze workouts not syncing

rhbrand

So I have a Blaze and when I workout, I start my workout timer and record my workout with that. After I sync my Blaze with the Fitbit app, I go to sync it with MFP app. However, there is no recording of exercise in MFP. Why not? It syncs the steps, but not the workout. Do I have to log in all my workouts manually? Cause that would suck cause I either lift weights, and I do a lot of sets, or I do Crossfit and that's hard to try to manually log in.
Is there a way to make my workouts from my Blaze show up? I've messed up a challenge on MFP cause none of my workouts synced up and I'm not going to go back and manually log in that many workouts.
