UI Error: Notebooks Will Not Open & Can Not Create New Notebooks

[istock-rpm]

Existing notebooks will not open in the UI showing Fabric logo indefinitely.

Can not create a new notebook.  Selection New >> Notebook returns me to the previous screen.

This behavior started around 3/12/2025 ~ 10AM CT.

Any ideas or is the Fabric team aware of this issue already?

Closing the browser and re-log into Entra Id resolved the issue.
