The request
“We use Klaviyo's back-in-stock flow. Another app we installed also adds a notify button and now they're fighting. Sometimes both show, sometimes neither. We want Klaviyo's only.”
Two apps both trying to own the same button. The brand wanted a single, reliable notify button that fed Klaviyo.
The approach
We removed the competing app's button, cleaned up its leftover code, and made Klaviyo's back-in-stock the only notify button on out-of-stock variants. Signups tested end to end into Klaviyo.
What we shipped
Competing notify button removed
Leftover code cleaned up
Klaviyo back-in-stock as the single notify button
