Can’t get it to do anything, just spins and spins. No instant summaries, no chat no nothing. I’m a developer, I have a fast computer, this is not user error

• Global semantic search across your PDF library (⇧⌘F) with cleaner, non-duplicated results and readable snippets
• Find in PDF (⌘F) with reliable next/previous navigation (⌘G / ⇧⌘G)
• Smoother zoom: zoom in/out + fit/reset feel more consistent, including trackpad pinch
• Onboarding overlay polish: clearer highlights and navigation
