I'm a little confused about your scenario.
Do you mean that the visaul header icon doesn't show in reading view in Power BI Service?
If it is, please check if you have turned off the icons under visual header.
If I misunderstood your scenario, please share some screenshots to describe your scenario in more details so that we could help further on it.
Thanks for replying. I had a lot of trouble getting back to post after the recent logon change to the forum (the PBI support staff were very helpful though) and I posted thsi without being clear. And in the wrong place (it should be servcies)
But yes the visual header icon doesn't show in reading view in Power BI Service?
and they are all turned on as shown in you screen shot
So it shows in edit view. But not in reading view. I will add soem screen shots below
By my tests, I cannot reproduce you issue in my power bI service.
Do you confirm that you have turned on the option under visual header?
Please have a test with my attachment in your power bi service.
In addition, you could clear your browser cache and try again.
Ive uploaded yours and can see the Icons. (in both reading view & edit view)
The only thing I can think off is Im using the new filter options. Maybe this has had an impact. The only reason I did this is because I wanted to see how the new 'filters and slicers affecting this chart' Icon worked. Its just what was needed although still very buggy. But I can only see it in edit view
Maybe in time this will right itself. Or maybe the filter Icon can be included in the right click options as well. Its a essential requirement IMHO to see all the filter and slicers impacting on a chart so hopefully this issue is rectified
But thanks for your help
