I recently bought a Garmin Vivoactive 3 and it is a nice device. While swimming indoors, sometimes there is a badly recorded interval. No problem at all. This can happen. But how do I now delete the badly recorded interval from this training session? Is this possible with any Garmin App or Website? Do I need to switch to a different Garmin Device to make this possible? I looked in the forums and this issue was raised before but most posts are 3 years or more old and might be out of date. Any support or knowledgeable person maybe know something? Many thanks!
