Why doesn't quick shop work on mobile?

Mobile screens have less space and different interaction rules. Many themes intentionally limit "quick shop" on mobile to keep browsing simple and avoid accidental taps.

What you can do instead

• Enable a "Quick add" pattern that doesn't require a modal (if supported)
• Use clear product cards that encourage product page visits
• Optimize product pages for fast variant selection

If it used to work and stopped

• Check if an app changed product card markup
• Validate there are no JS errors (browser console)
• Test with apps disabled in a duplicate theme
