Another factor for Microsoft to consider, is that when a user responds to this thread, they automatically receive an email with every new comment. This means that every person who has commented here receives multiple emails every day showing not just negative, but increasingly hostile responses to this feature. People used to say "I'll never use this," and then "I won't use Power BI if this becomes the only way," to now "I'm going to stop using Power BI because I assume Microsoft is going to make this the only way." Because we are all subscribed to this thread, this overwhelmingly negative sentiment multiplies in the hearts and minds of the core user base. It is painful to watch this go on for months without Microsoft addressing how they will turn this around, what the long term plans are for this feature, and why Microsoft continues to invest in such a wildly unpopular feature.
My opinion is that this feature is being pushed too aggressively and with very poor testing. After multiple crashes early on, I haven't touched it. Things like managing panes is such a basic usability issue, that I don't think Microsoft is doing any significant testing before we see it. While this is ok for small features that are mostly polished, this change is too big and too rough still. It feels like we are alpha testing, not beta testing. The whole world should not be your alpha testers! We are on a monthly release cycle, so by the time we give you feedback, it takes months before the fixes come back to us. That isn't workable for such a large change. At the pace you are on, it will take years before this change is usable. And you are depleting your pool of testers when people turn it on and have to turn it off after 5 minutes of testing. Many have made up their minds on this change by now and won't touch it anymore. How are you going to get feedback then? You need a smaller, highly active test group of seasoned developers who want this feature and a weekly release schedule. Pull the preview until your alpha testers are happy.
Something needs to happen though. Continuing on as-is hurts the trust we place in the development team. This thread is a festering pool of negativity. If you don't address it somehow, I think you will see the sentiment toward Power BI continue to decline with your core users.
