If you create #PowerBI reports with ANY Custom Visuals you MUST ABSOLUTELY stop what you are doing and read this blog posts by @marcorus from SQLBI & OKVIZ.

I wasn't completely aware of these process and I'll be talking with customers and making changes. https://okviz.com/blog/updating-power-bi-custom-visuals/

After reading Marco's article, did you learn learn anything?

If you use Certified Custom Visuals how within what time frame do you expect Microsoft to deploy bug fixes submitted by the author?

Maybe instead of "expect", I should have put "want", you may have low expectations, but want better?

Perhaps this is the one that still shocks me...
AppSource overides Organization visuals. I haven't used them up until this point but believed that Organizational Visuals would win... the version you have defined for your org would be the winner - Not the case.

Should an Organization be able to specify and over-ride the version of a visual to use in order to be able to work around breaking changes, also be able to apply private builds from the developer.

Feel Free to respond to the survey question, with concerns, with questions.

I would be great if there was some way to control in AppSource by crowd-sourcing to say "Hey, this new visual is all of a sudden causing a problem for our Enterprise" My enterprise has 470 MAU's so I get 470 votes (I don't know this, but quess who does...).

6 large customers speak up and can force a rollback through AppSource. Make the n-1 version always available and alert the developer. Developer lets Microsoft know that they're working on fix and give ETA. When fix arrives Microsoft has a SLA of 24 hours, but strive for 4 hours?
