ERROR. Power Bi Desktop November Update

With the last version of PBI if you change de data source to the same cube but diferent SSAS DB you will get an error in all visuals.

Until the October version that it's my way to work:

• Develop the report connected to a SSAS development cube
• Change the report to connect to a SSAS production cube
• Publish the report to the service.

Now, if you change the data source you'll loose your work.

Here you're this video with the problem: https://youtu.be/ojuHyOB43oA

Please help!
