Having this exact issue. With the new navigation UI/structure, I do not have “Library,” or “Marketing > Files and Templates,” or " Content > Files" available as selections.
So @karstenkoehler, am I understanding you correctly to say that HubSpot is AWARE of there being virtually no way for (some?) users to access their/our file managers… and are perfectly content to provide us with ZERO solutions or ways to remdedy???
