Apple Watch activities not syncing to fitness app

apple Watch series 4 and iPhone XS.

since updating both devices on Friday I’m finding most of my activities from my Apple Watch are not syncing to the fitness app. Some are and some aren’t and as of yet I’ve found no pattern. The information does seem to be showing in the health app but even then not where you’d expect. As an example the walk I’ve just done doesn’t show in fitness, doesn’t show in workouts in the health app when looking at watch data, but the amount I’ve walked does show in the health app. Rings are increasing, the activity shows in the watch, but heart rate doesn’t show in the activity either. Heart rate is being recorded though.

anyone else with issues? Already reset the watch twice, don’t really want to do it again.
