Lag, slow load, just spinning

I too have been experiencing issues since sometime around 8/26/16.

Around that day I noticed one of our larger reports was refreshing itself every 10 minutes all of the sudden even though it was only scheduled for once a day.  This is a report that has been in place for months using Power BI scheduled refresh and had been working fine.  Nothing about has changed from our side of the fence.

I entered a basic support ticket and got a response within a couple days telling me I was using refresh incorrectly and pointed towards the documentation.  According to the documentation, I was using scheduled refresh correctly so I highlighted that in my response as well as the fact that this wasn't a new report but something that had been working as expected since at least April if not earlier.

I sent my response on 8/30/16 and have yet to hear back.

In the meantime, on 9/2/16, we began experiencing refresh failures on approximately 2/3 of our reports.  All reports have been up and running fine for months with a daily refresh.  So 1/3 still refresh as normal, 2/3 have failed refresh since 9/2/16 to the point where Power BI disabled the scheduled refresh.  All reports are configued basically the same way.  Stored on OneDrive/SharePoint and connecting to the same Azure SQL DB.  The ones that failed scheduled also fail manual refresh now.  Removing the report and re-adding to the Power BI service hasn't helped.  All reports can be refreshed locally without issue.

We have many reports, so I have seen the occasional refresh failure but it has always resolved itself the following day.  I have just attributed it to server traffic and working out the bugs of a new service, but the fact that 2/3 of our reports all started failing at the same time leads me to have a much bigger concern with what is going on behind the scenes.  Something significant has changed in the last couple weeks.

I have updated my original support ticket twice now and still haven't had a response in over a week.

That is unacceptable performance and support for a GA product.  It is particularly troubling when there is zero communication.  It gives me serious concerns about the long term reliability of this product and our plans to incorporate it into our future roadmap.

As an additional note to anyone having similar refresh issues, the investment in Power Update might be worth it as a backup.  I have moved my most critical reports to Power Update for now and while it works well and keeps them refreshed, it isn't an ideal solution when I'm paying for Power BI to work as expected.  I hope this is only a temporary workaround.
