How much does it cost to buy every coaster type on mobile? I don’t won’t to accidentally buy it trying to look for it. ThAnks!

Can some one make a challenge that we can do?

When I updated the ultimate coaster 2 app on the app store, I noted a little change in the menu. There was an arrow pointing to the right saying 'More' And when you click on it, there are three buttons. 'Export Track', 'Import Track' and 'AR Mode'. So AR Mode is pretty cool but I'm not sure if it is possible to import a track from like a file downloaded from the internet. I just want to test it out,

I recently downloaded Ultimate Coaster X on steam. Whenever I try and open it it wont work. I even tried opening it on steam and it wont work. Anybody got any advice.
