I’m trying to sign into the 3D Warehouse page but I get an error from Google advising the service hasn’t been enabled for my domain (account is part of a Google Apps domain).
I am the Google Apps administrator and I can’t find any service not already enabled and I can’t find the SketchUp service anywhere in their app store.
if (google apps domain == google account)
SketchUp is neither a Google product nor a cloud app (that could be available in their cloud app marketplace). SketchUp just uses login via Google account verification. Probably that works by default only with normal Google accounts and not Google Apps accounts.
