Power BI Desktop November 2018 version - Backward compatibility
I always found this to be standard behavior. I have a particular report that has a bug using the Oct 2018 version, so I have to downgrade (uninstall Oct, install Aug) to Aug 2018 version to update that report, then upgrade again to Oct 2018 to edit/use all of the reports saved in that version of PBI Desktop.
To me the behavior makes sense as there are features in the newer versions that the earlier versions would have to "predict" in order to support.
I must have misspoke. I cannot open reports created in the October 2018 version with the NEW November 2018 version. Failure of backward compatibility is not something I usually expeience with MSFT products. In our case it appears to be those reports that used Direct Query. The error throws when the report is attempting to load the data.
