Synchronisation between Xert and Strava, when using Karoo2

Hello, using my Garmin I add a direct and perfect sync’ between the activities in Xert and Strava. Now with my new K2 I can’t manage it. How should I proceed?
Thanks for your help,

Pierre

Not sure what you’re referring to. Xert installs (via apkpure) on my k2 and syncs directly from the device (I think, since Xert doesn’t offer the sync to hammerhead option on their site). What is “perfect sync”?

Sorry for being unclear. I had a direct and perfect sync’ between the activities in Xert and the activities in Strava, i. e. they had the same title and description, as well as a direct link in Xert for viewing the activity in Strava, meaning maintaining the information in Strava only and it was automatically pushed/synchronised with Xert.
Now, when I’m finished in Strava, the title and description remain unchanged in Xert,m (default title).
