Import 2020 to 2021?
Gold 2021 1.0 is not importing income data from a Gold 2020 3.1 export file. I have checked the Gold2020 file and the data is there. I've also been able to open and save those export files in Gold 2020.
This is the type of problem that can really only be addressed by sending an export file to the developer at firstname.lastname@example.org along with a good description of the perceived issue. In this case, this was done and the problem was quickly resolved. It was indeed an error in PRC2021's import function and has since been resolved.
