Thanks, but we still don’t understand the error: “Invalid or missing build number in the VPKG”.
Here is the pertinent part of the manifest.toml which was used to build this:
schema-version = 1
[package]
...
version = "1.2.5"
...
In general, whatever the answer is, similar to the other issue we just reported errors like this need to be reported much earlier in the development process—at compile time and by the SDK, not at submission time & by the appstore.
