"For the screensaver setup in Launcher, I created a “Screensavers” folder in my personal OneDrive. On each display, I signed into its respective OneDrive account, shared my folder with that account via email, then downloaded it locally by selecting “Keep on device” and pointing Launcher to that file, this meant all displays automatically pulled content from the same live folder."
