disappearing sheet in workspace
I am working in a workspace shared with one other person, which contains a folder of reports and a dashboard only she and I see, as well as the underlying sheet that's owned by a different person and shared to a group of people.
The sheet keeps disappearing from the workspace on and off. Not only that, but my access to it seems to be switching on and off. I'm assured by the sheet owner and the other person in the workspace that they're not touching it.
I'm definitely on the sheet, but now when I go to my dashboard to check the sheet summary widgets, I get this message below (sometimes, not all the time!)
I looked in my workspace and the sheet is currently visible to me in that workspace.
Is this something to do with the fact it's been moved to there recently by me, but is still shared to the same group of people as before? Could it be because one of the users is moving it from their "shared" area into another workspace, or something like that? Perhaps I should get ownership and move it into a different workspace shared to the whole team.
If anyone's experienced this I'd appreciate any thoughs, thanks!
