Other activies that such from AXS should not be loaded form Garmin connect. E.G. data form stepper training.
When I connected SRAM AXS Web with Garmin connect, all activities form Garmin connect has been loaded, even such form the forerunner form my stepper training. This activities has Nothing to do with SRAM AXS, I would suggest that this data are not loaded to SRAM AXS web or that you can choose if it should be loaded or not.
