Filters - "Assigned to" not able to turn filter off
I am trying to look at an issue around a filter that is created in a sheet that is set to Assigned To current user, yes when they go into the sheet they only see the task assigned to them, but they are also able to turn the filter off and see all task in the sheet which we do not want.
I have added some screen shots that shows how it is setup (personal details have been blanked out)
There must be a way to stop the assign being able to turn the filter off, otherwise what is the point of it.
Thanks for your help in advance
