We have multiple reports publised that have multple pages. Starting this morning, the page listing that would normally appear to the left of the data is showing grey bars (see image below) and as a result, the reports can only display whatever page was last displayed.
The image below is from a very simple dataset and report that I created to test the issue; it's pulling from just one calendar table, and the graph is literally just a count of years for each month; so I don't believe it's related to data size or any sort of complexity. And we are seeing the same issue on all reports we have published. This of course makes the reports useless for our users.
If someone could please advise it would be greatly appreciated.
