Hello all

I have an iPad Pro 2017 12.9 inch. I had Artrage for iPad even when I had iPad Air - migrated the license from there.

I believe the present version is 2.4 as per Apple Store. And system requirement is iOS 10 or later.

I have iOS 11.3. (for reasons of my own I am not updating to latest iOS) iOS 11.3 should support version 2.4

But my Artrage shows it is 2.3. When I go to the App Store and search for Artrage, it shows up as "Installed".

So what could be the reason that it is showing 2.3 and did not receive the update?

Thanks in advance.
