Garmin Connect: I Named My Activity but It Still Shows Untitled
When a manual activity is created, your Garmin Connect™ account allows you to name that activity. However, if the Activity Name display preference is set to Untitled the name will always show Untitled in the “All Activity” list and Calendar.
To prevent this from happening, you can change the default activity name using Garmin Connect web:
From a web browser, sign into your Garmin Connect account.
Select Profile & Account.
Select Account Settings.
Change Activity Name to something other than Untitled.
