Thank you! I will be looking forward for your response.

User in my tenant is reporting he can't save edits either - is this related?

I too am getting the "Can't save dataflow" "Unknown exception" error.  Just started today.

In my case I am getting the "Can't save dataflow" "Unknown exception" error when I Apply a dataset to a trained Machine learning model.  I have encountered this error with two models today in separate Workspaces, one in which nothing has changed since I ran the model a couple weeks ago.  It seems there has been some kind of recent change in Power BI online that has sparked this error.  I have spent several hours trying to find a way around it but so far to no avail.  Don't know what to do, please help.  Thx

I'm getting the same errors when trying to save dataflows. Sometimes it's the "Unknow Exception" or this:

The dataflows then fails to refresh with a generical error: There was a problem refreshing your dataflow. {"RootActivityId":"b50f9052-b93b-d2fd-2c4e-cc250e1ffae3"}
