MapMyWalk data not syncing with Apple Fitness

I've been using MapMyWalk (both Apple Watch (ios 11.0) and iPhone (ios 18.0) versions) and Apple Watch Activity to track my workouts. I was playing with various settings the other day and now Apple Fitness is not updating the data from MapMyWalk. I must have turned off a setting somewhere, however, I can't figure out which setting. I've gone through all the settings in Health, Fitness, MapMyWalk, etc.

What else could I check for to get my Fitness app up to date?

Thank you
