Known Limitations

• Comments and Tags aren't included in the exports.
• Indentation outside of lists is not converted, because Markdown uses indentation only for lists and code blocks.
• Some items can't be converted if they are exported with the old note editor format. For example links in the format nimbusweb.me/* or some attachments.

If you have a backup including tags and note links (premium feature), feel free to share.
