Ever since I tried introducing PBI in my previous company, we struggled with sharing the outputs from PowerBI with our external clients - even those who were also on o365 and could already share OneDrive files with them, for example.
I happened upon this article the other day saying the external users will be able to be added to Groups.
Does this suggest that once fully rolled out, I'll be able to add an external user to a PowerBI group and share / co-author a PBI report?
