There should be a log file some where that keep tracks of users adding, removing, moving, editing settings, configs, or editing map configs/app configs within AGOL.
There has been a few circumstances where items go "missing" (deleted) that are in production and management wants to know who is doing this (but we dont know). Also, maps/apps get reconfigured with different layouts/colors/ pop-ups etc. and we want to know who is doing this and when they did. It doesn't have to be detailed (just say user x changed the map on x date:time).
I am not referring to editing data items I know that is already tracked.
