PowerPivot for SharePoint 2016 Bug - Snapshots only generate for localhost
I found a bug with PowerPivot for SharePoint 2016 and wanted to make sure it was brought to the team's attention. In short, I found that there's a hard dependency on "localhost" by the Excel Services REST API in SharePoint 2016. This means that workbook thumbnails will not generate in anything other than the first web app (if configured a specific way). I posted a blog with the details here: http://info.summit7systems.com/blog/bug-report-powerpivot-for-sharepoint-2016-thumbnails-not-generating. Support case 117021415318755 was created, so hopefully the bug report was submitted through it.

BTW, I initially posted this back in March, but I screwed up with its title and thus I'm sure nobody read it. I deleted the old one.
