Unable to save notebook error

Hi alee023 
Thanks for using Fabric Community.

Here are a few troubleshooting steps you can try:

Refresh the Page: Sometimes, a simple refresh can solve the issue. If there’s a temporary glitch in the system, refreshing the page might help.

Check High Concurrency Mode: The error “Unable to fetch high concurrency mode enabled info” suggests there might be an issue with the high concurrency mode of your notebook. High concurrency mode allows users to share the same Spark sessions in Fabric Spark for data engineering and data science workloads. You might want to check if this mode is enabled correctly.

Check Notebook Saving: The error “Unable to save notebook” could be due to a variety of reasons. It could be a temporary issue with the server, a problem with the notebook itself, or an issue with your browser. Try to create a notebook after sometime because this might be due to a temporary glitch.

Please check the above mentioned troubleshooting steps. Let us know if the issue still persists.

Thanks
