I can't buy any aircraft at all

[Tui_787-8]

so the only planes I have are the one’s that come with the game. Is there any way to make the work.

The ability to purchase individual aircraft has been removed. You’re now required to purchase a pro subscription.

Previous purchases are grandfathered in for you to download.

Hello!

It looks like you are using an older version of Infinite Flight. In-app purchases are no longer supported. You will have to upgrade to a device that supports the Global update and buy a subscription. It will allow you to fly every single plane in the app and gives you access to the entire globe!
