Judging by many complaints on their telegram group, the app is still not availble in most countries. I hope they will fix it soon, because restricting it only to US region doesn't make any sense, especially in crypto space.
I think the application should work for any region of the planet, otherwise such inequality will result in discontent. Also, it will not allow all interested people to invest in the project.
Hopefully this is a bug with the application restriction by country. Because it cuts off the huge investor market on the platform. I am very interested in this project, and in the future I want to invest in compositions of famous artists.
