Information tab and Filter box empty in Analysis

Hi guys,

We are experiencing an intermittent issue where sometimes the Information or Analysis tabs are empty despite the crosstab being connected to BW. Sometimes the Filter box is also empty.

It's not always possible to replicate the issue and not every users gets it. It's been fine for over a year but has just started so I suspect an update to Office 365 or Windows?

Has anyone else had this issue? Users are on Analysis 2.4.3

Regards and thanks in advance,

Stephen
