I am the owner of an ArcGIS Online group. When members try to share the content they have created to that group, it is not an available option for them in the list of groups they can share to. In fact, having just checked, it is not even an available option for me.
Any tips as to settings that I need to check, either on the account or on the group, would be really welcome. Here are the group settings at present:
All accounts in question are members of the same organisation.
EDIT: I think it is to do with the "Members can update all items" setting. If I create a new group without this setting, members can share items to the group. Can anyone point me to documentation which explains further?
