What is going on with different Jupyter notebook experiences in VSCode?

[TestMannequin]

I am having trouble tracking down why my editor has changed, I love the old one, hate the new one. And oddly, I can run both at the same time.

Old:

New:

How do I control this behavior, I have looked around for quite some time to find what is controlling this setting.

Thankyou for any help or ideas.

This is best asked at https://github.com/microsoft/vscode-jupyter as that's the Jupyter extension, but basically the Jupyter extension now uses a native/integrated notebook experience/support from VS Code itself and you are probably jumping between the A/B experiment that is controlling the rollout of the new experience.

If you have feedback about the experience then please open an issue on https://github.com/microsoft/vscode-jupyter.
