I noticed since the Nov update that if you edit the data source settings when connecting to SSAS Tabular (don't even change the settings just open edit connection and then click OK to all the values without changing them) when the page finishes refreshing all the visuals are broken.
This never used to happen prior to the Nov 2017 release, is anyone else experiencing this?
Please click file->Options and Settings->Data source settings, clear permissions. Then type your SSAS credentials to check if it works fine. Power BI Nov verison works fine my my local computer after test.
