I asked a question on the forum about why activities from my FR60 won't show in the rss feed on Garmin Connect. You can find the thread here: https://forums.garmin.com/showthread.php?t=15318
I didn't get any answers so I contacted Garmin Support directly and eventually got this answer
Thank you for contacting Garmin Europe.
I am sorry for your difficulties. Having researched your problem
further, I have discovered that you require a GPS log to use the RSS
feeds. So I am afraid your cannot use the FR60. These rules apply for
any activities in the RSS feed:
? It is a GPS activity.
? Activity Type is categorized (e.g. Trail Running).
? The activity has an Activity Name (e.g. Tahoe Rim Trail).
? The activity is Public.
I don't really understand why you should need a gps activity for the rss feed to update properly, so my feature request is simply to enable the rss feed functionality for ALL devices.
