Mobile has audio-only "Ideas con Bea" and others, but Desktop does not.

I actually like the audio-only "podcasts" with Bea and Zari*, and it looks like these to what I would see on desktop. I switch between the two platforms a lot, and I'm sometimes confused about whether progress has been tracked. Anybody else choose one platform or the other to avoid/seek these lessons?

I'm on sec. 4 unit 29

*I don't care for the ones with Junior. His voice doesn't seem the same as in the regular listening lessons.
