I am experience the following issue since a while:
- create a simple report on top of a SSAS Tabular model via DirectQuery in the PowerBI Designer and publish it to a workspace in PowerBI (it also works for a regular model)
- click on the report or dataset in PowerBI (everything runs fine)
- create a contentpack with the report and Dataset and share it with another work-space via its email address
- go to the other work-space and get the content pack
- the report and Dataset become visible
Now the reports works fine, however when clicking on the Dataset to add a new report, nothing happens. Previously the 'Shared with me' icon became automatically visible and you could start using it to build reports in the work-space.
The only possibility you have is to create a copy of the Dataset (and remove the original one from the content pack to avoid confusion). Then you get a personalized version in the workspace. However you can't change the name of the Dataset, so it's always called 'NameOfDataSet - Copy'
Please revert the old behavior: clicking on a shared Dataset immediately makes the Dataset 'shared with me'.
