Cannot see Q&A question box

konstantinos interesting... i have not tested the caching situation. 

I am going to go on a wild speculation here, but the fact that Q&A works at all implies that there is an AS (direct query mode ???) model sitting between visuals and SQL Azure.  Since Q&A is a meta data driven technology that depends mostly on the semantic model and to a lesser degree on the actual data in the model (although again, there is a fair amount of speculation in that statement) I think it is not beyond the realm of possibilities to assert that Q&A should in fact work with SQL Azure and the caching problem that you are seeing is related to the data set overall and not Q&A per se.

At the same time, it is all one huge wild speculation and it would be interesting if MS could shed some light on the situation :)

Since PowerBI service direct connection to SQL DB is a live connection like SSAS , maybe don't support Q&A..

Not tested yet..
