How do I change background colour for exporting pdf?

When I export a pdf (I happen to be exporting various focus mind maps, only the mindmaps) in MN4 iOS app, it always has a grey background to the pdf. How can I change the settings so that I end up with a white or transparent background? I like to print my exported PDFs and don’t want to have to ink the whole page grey to get a printed copy.

Hello

We understand your needs. Currently, we are unable to change the background color, but we have recorded this issue and will report it to the developers.
