Starting May 1, breathwork activities (sportid 857546?) are no longer synchronizing from Garmin and manual FIT import reports an error icon—no error text provided by the current import tool. FIT files show software_version changed from 1622 to 1715 on this date but nothing else seems obviously altered in FIT files after April 30th. Other sport types continue to import without issue.
The old import tool is able to import these activities without error but is initially missing most activity data (e.g. HR, RR). This also is correctable using "merge file into activity" on the activity's detail page. While this particular sport type isn't vital for me to have in Runalyze, most of us can appreciate a complete dataset! FITs are available for review as needed.
Regardless of this one "bug", thanks for making available and maintaining such a fantastic product!
