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.
