Custom Visual Timeline Slicer Does not appear to work when using SSAS Multi Dimensional as source

Hi Microsoft / Baskar,

I share your concern Baskar to a degree, although lets not throw the baby out with the bath water!

So in response to your recommendation Baskar, I have created a dashboard based on AdventureWorks. I noticed that the custom visuals Smart Filter, Hiearchy Slicer and  Timeline slicer all work perfectly within Power BI Desktop within an In Memory model. 
I need to test how they work within one custom visual for each report when deployed to PowerBI.com whilst connected to an SSAS Multi Dimensional Cube.

Getting back to my initial point I also think we need to consider who has created the custom visual when choosing to use the custom visual. If Microsoft has created the custom visual themselves then there is a higher probability that this custom visual will work with the next Power BI dashboard version.

I also think it's important to have contingency planning, e.g. have a alternate pbix file with the standard text drop down in place of the pbix file of the custom visual in the event the custom visual smart filter does not work.

It's just that custom visuals are a signficant feature in what attracts people to use Power BI in the first place.

Microsoft, please give the Power BI community ..

1) Clear guidance when and when not to use custom visuals.

2) As custom visual developers how can we ensure that out custom visuals work within the next release of Power BI dashboard.
