Notebook Options

• There is a known issue where the Jupyter Variables and Restart Kernel buttons do not always appear in the notebook options.

Kernel

• There is a known issue where the kernel may become unavailable when returning to a notebook after a period of inactivity. In such cases, it is not possible to reselect the kernel. If you encounter this issue, refresh your browser to continue working in the notebook.

Cells

• If you update an existing Python cell to be a Markdown cell, it doesn’t render as Markdown.
• The border and type of cell on Markdown cells aren’t displayed.
• The error output in cells doesn’t render HTML content correctly.
• Some keyboard shortcuts for navigating and working with cells do not work: M in command mode for changing a cell to Markdown, D+D in command mode for deleting a cell.
• When you have truncated output in a cell, the Adjust cell output settings option in the output displays an error.
• There is a known issue where dragging cells in a notebook can cause the output in other cells to not display. If you encounter this issue, restart the kernel and rerun the cells to see the output again.

Browser-Specific

• Dragging and dropping cells in Safari doesn’t work.
