Slide-specific timingYou can override the autoplay timing on a per-slide basis. This option is available within the Slide Settings menu.
If your presentation will run in a kiosk/information display setting you can make the presentation reload automatically to ensure that any edits you make are visible. This can be enabled using a query string parameter called "autoRefresh" which accepts a number in milliseconds (1/1000 of a second).
For example the following will reload once every ten minutes: https://slides.com/news/make-better-presentations/fullscreen?autoRefresh=600000 (10m*60s*1000ms = 600 000ms)
