Debug Cell option disappears arbitrarily

[epicwhale]

Applies To

• Notebooks (.ipynb files)
• Interactive Window and/or Cell Scripts (.py files with #%% markers)

What happened?

Sometimes it shows the dropdown arrow with Debug option...

And sometimes it does not...

This is quite flaky and I can't figure out what's causing it.. pasted logs below
