Not able to delete or update connection string of dataset using Azure analysis services server as data source

I have issue in deleting dataset with live connection to data source. Is there any work around to solve this issue?

• Power BI Embedded is not yet supported in preview, so make sure that you are using GA version.

Regarding the origin issue you mentioned I have had the same issue.
I solved it by this workaround.

1. Create a new workspace collection
2. Create a new workspace and upload pbix file with Direct query( so I have one dataset within workspace)
3. Use ProvisionSample tool (remove first all configuration for app config) to update the connection string.
   3.1 Enter user name
   3.2 Enter user password
   3.3 Enter connection string in the format : Data Source=xxxx.database.windows.net;Initial Catalog=dbName;User ID=xxx;Password=xxx

Let me know if it work on your side.
