I've noticed that all of my published reports are facing this issue. I have tried to published then again and new ones, but it's still the same.
All works fine in the desktop, but it doesnt work on the service.
My cluster region is UK South (London).
Anyone else is having this issue too?
Based on my test, both default tooltip and report page tooltip work in Power BI service. Please test again on your side. If the issue still occurs, please create a support ticket to get help.
