gigi8703 aske a question in Italian again. He says when sending exact power to Garmin it gets lots of warnings, is that normal. Because you are never training at an exact power but exact power makes sense from an ERG stand point. I don’t actually know the answer but I would try using 10s or lap power like the attached screenshot.
Is sufficicient to disable target alert in the activity profile.
Sending the activity as exact power and 3s power i had not problems.
