Bug Report: ”XC Ski Indoor" activity does not sync to any connected third-party app (Strava, intervals.icu, Runalyze)

Activities recorded with the "XC Ski Indoor" profile record correctly and appear in Garmin Connect with full data, but they are never forwarded to any connected third-party partner (Strava, intervals.icu, Runalyze). Every other activity type from the same watch syncs normally.
