I got a training plan in my device (forerunner 620). I deleted it in Garmin connect and made a new one. I sent all the training plan (49 training days) and Garmin connect said it was ok (put into the 620). I ejected my watch from the mac and looked at the Training schedule, and i have not the old training plan, nor the new one. Nothing. And it tell me : download your training plan from Garmin Connect.
I have made it twice and always nothing.
But i find the issue.
I created a training of mine, sent it and now i got all the 50 training days (49+1).
Strange bug.
