I understand that creation of PPT takes time and we need to wait for 15- 30 min after data refresh before initiating the export.
I refreshed the data 2 weeks back and initiated export a day or two back. However, the export did not correctly create shape map visual (map was missing only markers were present). Sometimes other visuals also fail.
I tried exporting the ppt again. This time some other visuals which took a tad longer to load did not work correctly.
When used with Direct Query, this behavior is much worse. Many visuals appear as blank.
Please make sure that export works fine. This is one of the very imortant feature for some clients.
