Importing structured workouts from Trainingpeaks to Garmin connect (935)

I own a 935, and I'm trying to export my workout from TP to my garmin connect phone app (and from there to the 935).
I have the TP's conenct IQ installed and everything is okay, but every time I try the Connect app opens in my favorite routes tab (even though it's a workout and has nothing to do with a route), and there's an error message showing.
I tried to get support from the UK support, but their answers led me to believe they are not Garmin users... :(((((

I've watched the tutorials, I've searched the web, nothing solves that bug.
Any ideas of how to solve that?

Thanks in advance!!!
