I created a dashboard with pieces of some reports, but when I change the tiles of position, they return to original place, I tried to refresh browser, logout of user, change the browser, I just tried with IE, Edge and Chrome, and all of these have the same behavior.
I don't understand the real cause of this, it's very strange and this is drive me crazy.
Maybe it can be a bug?
Thanks in advance.
I was unable to reproduce this problem on my side. Have you tried to remove and re-add those tiles to dashboard for a test?
