Was this posted somewhere? I find little reference to it besides here. I sure have a lot of Yousician emails, but none mention "linux". As something I'd paid for, I think there could have been a better heads up when dropping support for the only platform I use it on.
I got the yearn to play again and maybe buy a subscription, but now there is no Linux support. I will restore my guitar in the cellar again, or trying to looking for another service. Yousician is great, but is not an available option for me now.
