Error when connecting to SQL server analysis services database

Is there any resolution to this in Power BI updates since this post. We are also facing the same issue with loading more data from Mutidimensional SSAS cube into Power BI. We need to use DAX to acheive the desired customization in Power BI. Hence need to go for Import Mode. Is increasing MemoryBufferLimit in SSAS a recommended and tested option. We need to do impact analysis if at all needs to change settings for SSAS standard installation.
