Still can't upload audio files

This is for support team. I still have not had success adding a url for audio file to my imports. It really has taken away from effectiveness of lingQ and will have to quit the app if it is not made easier to import audio to lessons. I listen to RadioAmbulante Postville, Iowa - Cómo una redada de ICE cambió un pueblo - Radio Ambulante all the time and they have great transcripcions for all podcast but cant get the podcast audio to work on LingQ? I have tried my imac and iphone. You need to make this easier or have tutorials.

You will need to add direct audio link to make it work, or I see there is also possibility on their site to download audio and upload it: Postville, Iowa : Radio Ambulante : NPR you will see the download option under the Play button.
