Fix common Markdown Editor problems

A document won't save

• Look for an error toast — the editor tells you when a save fails instead of failing silently.
• The usual cause is full browser storage. Export a .zip backup, then delete documents you no longer need.
• Copy your current text somewhere safe before troubleshooting further.

My notes disappeared

• Don't panic, and don't keep typing. Follow the dedicated guide: Recover lost notes.

Import fails

• Only markdown files are accepted — the file must end in .md (any capitalization is fine).
• Exports from other apps sometimes use .txt — rename the file to .md and try again.

Math or diagrams don't render

• Both are off by default. Turn them on in Settings → Writing tools.
• Check delimiters: $...$ for inline math, ```mermaid fenced blocks for diagrams.

The preview looks different from GitHub

• The editor renders GitHub-flavored markdown plus extras (footnotes, front matter, highlights). Front matter between --- fences is shown as metadata, not text.

A feature seems missing on my platform

• It isn't — every feature ships on every platform. If something looks absent, update to the latest version from your store; older versions predate the newer tools.
