Google Slides may lead you to believe that you can loop your slides without turning auto-advance on. After all, you can uncheck auto-advance time intervals while still having “Loop” on within the auto-play settings. However, loop doesn’t actually work without auto-advance. This can be a little inconvenient, especially since auto-advance doesn’t offer custom time intervals. Nevertheless, you can still go back to the beginning of your presentation without looping by pressing your number 1 key and hitting Enter.
