The dashboard seems to be full of ‘edits’ for which no changes were made directly. This happens after viewing ‘Compare with FamilySearch’. I can’t say for sure whether it happens every time, or whether sometimes there is an update in the background when the compare is done (eg there is more info on FS?) and that update is being identified on the dashboard as an edit.
I am focussing on collaborative management of trees, and having a meaningful dashboard history will help greatly with that.
