Pro 3.5
This has happened to me a few different times over the years and each time it has been very embarrassing.
Why is it that packaging (layer package, project package) doesn't consistently (or at all) actually package the data?
I packaged an mpkx the other day and was able to unload it successfully, but when I turned that same project into a ppkx, the recipient didn't get any data with it.
I've had similar results with layer packages.
What's going on?
Package Project (Data Management Tools) | ArcGIS Pro documentation
what wasn't in the ppkx that was supposed to be given the guidelines in the help topic.
I don't see anything specific in the public facing support site.
