Preview Markdown - Syntax highlighting (fenced code blocks)

[seaspeak]

Problem to Solve

Fenced code blocks cause error.

To Reproduce

use the following text, and then preview it

```python
import sys
```

Expected Behavior

It is extended-syntax (https://www.markdownguide.org/extended-syntax/#fenced-code-blocks). Some will colorize it, like github; or ignore it.

Screenshots

Environment (if applicable)

• OneNote Version: Office 2021 64bit
• OneMore Version 6.4.0

Additional Context

I really want to update my OneNote version, but this is the latest version available in my channel.

Might be an installer problem. I'll have to check it next week.
