I will fix shopify horizon theme mobile glitches and variant bugs

About this gig
Every hour your Horizon store glitches on mobile is an hour of ad spend wasted.
A customer taps your Instagram ad, your store freezes inside that in-app browser, and you lose them for good. Or your variant swatches won't update the image or price, so buyers assume you're broken and bounce before checkout. These are specific, documented Horizon bugs and I fix exactly these, not generic setup work.
What I solve:
- Frozen Horizon storefronts inside Instagram/Facebook in-app browsers
- Variant pickers that won't swap images, IDs, or stack correctly
- Broken image grids on mobile and foldable viewports
- Native Liquid badges & back-in-stock alerts zero app bloat
- Safe Dawn-to-Horizon migrations that keep your SEO intact
I read your actual theme code first, test every fix on real devices and in app browsers, then send a before/after recording so you see it working before you approve delivery. No templates, no guesswork.
Clear communication and fixes that hold up under real traffic that's the standard.

FAQ
My store looks fine but breaks when I click my Instagram ad — is that a Horizon bug?
Yes. This is a known Horizon issue with in-app WebView browsers. It's not your ad or your phone — it's fixable.
My swatches change color but the image doesn't update — can you fix that without a redesign?
Yes, it's almost always a JS binding issue between the swatch and image gallery. I patch the script directly.
Will fixing bugs affect my existing customizations?
No. I isolate the exact section causing the issue and test in a duplicate theme first — your live store stays untouched.
I need "NEW" badges and back-in-stock alerts without more apps possible?
Yes, that's a core service. I code these into your Horizon Liquid sections with zero added app weight.
Can you migrate Dawn to Horizon without losing my SEO rankings?
Yes. I manually remap sections, metafields, and URLs so rankings and redirects carry over intact.
My product grid looks tiny on mobile/foldables — what's causing that?
Horizon enforces strict CSS breakpoints that misbehave on certain viewports. I adjust that logic without breaking desktop.
What if the issue is bigger than expected once you look at the code?
I'll tell you upfront before doing extra work — no surprise scope creep, just a clear quote first.
