We are running analytics on our user base from the data stored and collected that is download able via the admin tools. We recently found that discover usage is not included in this.we believe many of our users use discover but we can get no insight on their actions.
When you mirgrated data from one user account to another, you are not able to delete the assets (segments, discover reports etc). They get stored forever and increases the mess you have to deal with. ThanksEddie
