Workout data on elemnt app

Just noticed that indoor workouts that I have done in the Systm app are not showing on the history page in the Elemnt app. All is ok up until the 21st July and today’s outdoor ride from my Bolt is there too but 22nd July to now indoor rides have not synced. Any ideas why or how I can get them onto the apps history page ? thanks

This has happened again after the minions had sorted it the last time. Last sync was 15th August. Anyone else getting this problem? Thanks
