Incompatibility issues when exporting to MindManager 2020

Hi, I’ve been having problems when exporting to MindManager 2020.

This is the error I get:


I enjoy this app enormously but MindManager have been my knowledge repository for years, so I won’t change it. Please fix this and make Marginnote a dream come true.

Hello, please also use other similar apps to convert the format of the brain map for the time being, MindManager 2020 is a bit problematic, still compatible in it!
