Why do I need "Browse & Access" turned on, and what is it?

Browse & Access is a built-in Supernote feature that lets it share its files over your local Wi-Fi. The app reads your handwritten notes straight off the device through it — that's the way to get the very latest ink, and the recommended path. If it's off, the app can't fetch the newest version, but it can still show any copy it already saved, and it can offer to download the note's last-synced copy from the Supernote cloud as a fallback. It's read-only: the app only reads files, never changes your Supernote.
