Which one did you buy?
And are you a free or a pro member?

I bought singer-songwriter, and maybe folk..pro member

I bought it too. because this came up very recently.
And I have it, too, has not yet appeared among the available.
so it was with the previous purchase of a training artist.
I waited a week and opened a support ticket today.
no answer yet.

if you bought it recently - then wait a bit.
if a long time ago - you can also open a ticket.

if everything is as it should be, then the purchased artists automatically become available for selection in your exercises

Thanks Ziggy! Well, I bought it a while ago. So write to some kind of support then..?

He just asked the question here Anton hahaha

Anton hi!
How are you? appeared previously purchased artist?

I wrote a letter to support to ask why the sounds I bought didn't show up in the choices. They never answered it so I don't spend the coins anymore. They don't appear to have any actual value.

Sean I think it's just a technical problem.
I already had it 2 times. Both times it was resolved through a ticket. The answer to the ticket is in a few days.
This time I received a reply within 3 days. the fault has been corrected. new music is already available in workouts

Yep, the sounds appeared!
