Here are some comments related to issues I've come across with the "Merge File" capability. I'm aware it's still in beta, so this is more feedback to the development team to help iron out issues and/or understand what I may be doing wrong.
a) CIQ fields from a Core BodyTemp (developer_CIQ_core_temperature) that are in the Garmin generated FIT file isn't displayed if this is not the first file uploaded/sync'd for a given event.
b) If the initial file uploaded is the Garmin one, then all the fields are available
c) In both cases, other developer fields such as Moxy SmO2 developer fields are correctly processed and displayed
Has anyone else had this issue?
