I understand for the changes after sync. Even if sometimes, once you uploaded your data, you make some changes. As the sync is quite in real time, the changes are never taken. It would be great that Garmin made a choice on an activty "Ready to sync with app"
For the second point, I'd rather say : getting title (from Garmin or others), if no put the default as "Place - Sport"
Just a question : you don't get the title because it's not possible or because you miss it ?
