Any help greatly appreciated.

Hi @blabrom Thanks for posting your question in Microsoft Fabric Community

It seems like you are having trouble editing any notebook created in Fabric. As per the error message it seems to be a connection issue? have you raised any support ticket on this?





Hi @GeethaT-MSFT


Thanks for the swift response. Given Fabric is in preview atm I assumed this forum would be the most appropriate place to raise an issue, but can raise a ticket if Fabric in preview is fully supported.


Let me know your thoughts?
