Technical issue with the "add to cart" button

Technical Q&A

Topic summary

Issue: On mobile, selecting a sold‑out product color does not update the button label to “Sold out.” Instead, the “Add to cart” button turns gray and becomes unresponsive. On desktop, the label changes correctly to “Sold out,” indicating proper state handling.

Additional behavior: After switching from a sold‑out option to a pack/variant that was recently in stock, the mobile button remains gray (disabled) until the page is refreshed. This mismatch suggests the mobile UI state isn’t refreshing after variant changes.

Evidence: Two screenshots provided (mobile and desktop) are central to illustrating the discrepancy.

Scope/Context: Affects mobile only; desktop works as expected. Tags indicate relevance to sales channels.

Status: No fix or workaround provided yet. The user is requesting assistance; the issue remains open and unresolved.

Hello!

I’m experiencing a technical issue with the “add to cart” button on my mobile device. When I select a product color that is sold out, the “add to cart” text doesn’t automatically change to “sold out” as it does in the desktop version. Instead, in the mobile version, the button turns gray and becomes unresponsive, but the “sold out” text doesn’t appear.

Additionally, if I try to change the product pack to one that was in stock just a moment ago, the “add to cart” button remains gray and unresponsive. To resolve this, I have to refresh the page. This behavior is not consistent with the desktop version, where the “sold out” text appears automatically.

I appreciate any assistance in resolving this issue. Thank you!
