Whenever I try to add new data to the model in DirectQuery mode I receive the error stating "Sequence contains more than one element", which makes no sense and there isnt really anything online that would suggest a workaround. I assume it just means Power BI Desktop is broken.
If I rollback to previous version I have no problem. Although I have to rollback 2 versions as the January update had it's own problems with DirectQuery. I want to use functionality in February version, so quite frustrating to be uninstalling and reinstalling versions just to add data to my model.
Have sent a frown and it states that it is a known problem being worked on. Would like an update here.
