Just add autoPlayLoop to Deck (as in documentation) - expected to play slides in loop.
Doesn't do so.

Thank you for the issue report.

I have confirmed this in some recent work of mine as well. There is a straightforward issue with stale references to a variable (navigation.isFinalSlide in this code) that, if resolved, will fix the main issue.

There is one more issue, however, that I noticed upon investigating: the logic in that hook will loop around to the first slide regardless of any Appear/Stepper-like components existing on the final page, so they will get skipped over without ever being shown. The total number of stepper-things in each slide is stored a little bit deeper in the component hierarchy than the autoPlay logic, so there may be some fairly involved refactoring necessary to get that part working.
