Troubleshooting
The slider doesn』t autoplay:
Check the block settings and ensure 「Autoplay」 is toggled on. Autoplay is disabled by default for accessibility reasons.
Keyboard navigation not working:
If multiple sliders are on a single page, ensure you』re using version 1.1.0 or later (this fixes navigation conflicts).
Layout issues on mobile:
Try adjusting the 「Slides per view」 setting or resetting custom CSS if applied by your theme.
