Share your thoughts on DirectQuery for Power BI datasets and Azure Analysis Services (preview)

For those that might have missed it:

Update December 18th 2020: we have just released Power BI Desktop version 2.88.702.0 which fixes the two most common issues we have seen being reported:

• As part of this feature, significant changes were made to the authentication flow for live connections to Analysis Services which applies even when you do not have this preview feature enabled in Power BI Desktop. Users were not able to recover from entering incorrect credentials or selecting the incorrect credential type and would see error messages such as 'Unable to connect'. You can now either select 'Retry' or use the Data Source Settings dialog to update your credentials.
• Converting from a model that is live connected to a DirectQuery model failed if the model contained a measure-only table and the following error message was displayed: 'The given key was not present in the dictionary'.
