Activities not syncing

My Apple Watch has stopped syncing workouts. It was fine then only synced a piece of a workout (no map only distance data) and since then nothing. When I save it, it says uploaded, but it doesn’t appear in my workouts. I have tried everything and many emails from help, but they just keep getting closed and nothing gets done. It is really frustrating and I didn’t change any settings it just doesn’t work anymore. Anyone else having similar issues, or suggestions. I also uploaded some pictures recently, but they aren’t in my workout, but appeared in my mates. Surely there is a data issue here. Like I say Strava help and Twitter haven’t responded, maybe Strava community will know what to do. Thanks
