Supported features

  • Collections: Previously saved articles will appear and you’re able to browse your collections. However, adding or removing articles doesn’t work without an active internet connection.
  • Notifications: Previously received notifications will be displayed and can be read. However, notifications read while in offline mode will not be marked as read for later, and cannot be starred without an active internet connection.
