I cannot load my gps rides into the the Tacx training app

I believe that while they are visible in all Tacx Apps you can only upload them via the (Windows?) Desktop App and while anyone can upload a GPS ride you have to have a premium subscription to actually ride it in the TACX App

Thank you. 
I have the Garmin Connect app and the Garmin Tacx training app on my IPad.

I also have a free 30 days trial of Tacx Premium but in the training app is says that I have no Premium account.

Hi! Is it not possible to do it from the Mac Desktop App?

Thanks for reaching out!

(EDITED) Riding Creating custom GPS workouts is a paid feature available with a Premium subscription. Creating custom routes and sub-courses is only available within the Tacx Training Desktop App (Windows).

(EDIT) Mobile and Mac users have the ability to import custom routes to their account using the Tacx Cloud: https://cloud.tacx.com/#/import-file
Self-created routes can be found under: New Ride > GPS > My GPS Rides

Creating a Course in The Tacx Desktop App

We are currently expanding integration of the Tacx Apps and Garmin Connect and may allow for more GPS course compatibility down the road.

This is a standard answer I keep seeing in multiple threads for riders with the same issue. It is not acceptable when you demand a subscription to use GPS routes in the iPad Tacx Training App. I've wasted hour trying to get a route for an upcoming ride to show. The iPad app should either be able to upload GPS routes if you have the subscription, or there should be a companion Mac equivalent, or even just allow it in a browser. If I'm wrong (and happy to be if I missed the way to do it), then please provide guidance to resolve it other than say you need a Windows device.
