The current version, available from other than the Marketplace, is 2.0.
No, it's not. According to the FSDT Installer, the latest version is 1.3.0.
You are probably confusing the product NAME, which is "Vancouver V2", with the version, but "V2" indicates it's a remake of the original version made for FSX/P3D. All our products that originally had an FSX/P3D version has a "V2" in their name, to make it clear they are remakes, which sometime even have an upgrade price.
Is the Marketplace version up to date?
Yes, version 1.3.0 of "Vancouver V2", is the latest version for MSFS, and it's the same here and on the Marketplace.
I find the gates to be abysmal.
Please clarify exactly what do you mean.
