Basically what the title says. If I search for any android library (e.g. support, picasso etc.), the thing on the right of the search field turns for about a second and then nothing.
I can only add the default libs you see when the dialog opens.
Is this a bug? Something to do with my network settings (manually typing in the compile statement in build.gradle works fine)? Something to do with file system permissions? I'm on a Macbook Pro.
I've tried resetting the cache and restarting Android Studio. I'm on the latest stable version (3.0.1).
