@PBIuser01, what browser are you using? If Chrome, I suggest you run the reports in incognito mode and see if the problem still occurs. If the reports run OK in incognito mode, then return to regular Chrome and purge your browser cache, then try again.
I experienced the same issue you're describing after completing the upgrade, as did some of our business users, but only in Chrome. Using incognito mode will give you a hint as to whether it's a problem with your browser, and purging the cache should remedy the issue.
We just published an update that addresses this issue as well as some rendering issues, you can get it here:
Just looking at the Change Log and the latest version listed is:
1.3.6816.37243 (Build 126.96.36.1997)
However the version I downloaded based on the announcement in this thread is:
1.3.6813.37954 (Build 188.8.131.524)
This version is not listed in the Change Log so am unsure of the differences between the two but have now upgraded to the latest build.
Possibly others may also be unaware.
