Lost Notebook Changes in Synapse Data Science (Microsoft Fabric)

Hello Fabric Community,

I recently encountered an unexpected issue with my notebook in Synapse Data Science (Microsoft Fabric). Despite having AutoSave enabled, I lost all the changes I made over the past few days. Strangely, only a few code snippets from five days ago remain. 🤔

Additionally, I couldn’t find a history tab for my notebook within Fabric.

Has anyone else faced a similar problem? If you’ve found a solution or have insights to share, please join the discussion.

Tdoay, when opening the notebooks from Fabric, got the message "Your notebooks currently have limited notebook functionality due to network issues. You can still edit, run, and save your notebook, but some features may not be available. Please save your changes and refresh the page to regain full functionality."

After multi refreshing the page, the issue still exists.  What's the network issue, who will fix it? Micrsoft or my company's IT team?

Chiming in here for lack of better ideas. I've also had some issues with losing notebook work in Fabric. Possibly for different reasons (I think mine were induced by having multiple connections to the same notebook accidentally in a hybrid work accident), but I find the work recovery abilities for notebooks in Fabric subpar. I submitted an 'idea' for Fabric to automatically and/or on demand checkpoint notebooks. This is already a default feature of Jupyter Notebooks and is integrated with notebooks in Azure Machine Learning, but is missing in Fabric notebooks.


Microsoft Idea


AML has a description of its checkpoint behaviour here: Run Jupyter notebooks in your workspace - Azure Machine Learning | Microsoft Learn . I don't see why this wouldn't be implemented for Fabric as well.
