Hello,
This is a message from the Dynamics 365 Business Central development team for all partners / customers that do use the PowerBi connector with Dynamics 365 Business Central.
A recent bugfix caused an unexpected behavior in the PowerBI connector. We have identified the repair items to be implemented in another hotfix. Until then, all PowerBI connections might be affected, but a workaround exists: the customers need to manually re-select the environment they want to connect to.
When there is more information, we will post it here.
Thanks.
