Your plan.
The listen feature is available on the Starter, Growth and Pro plans. On the Free plan the button does not appear on the storefront, even though the block can still be placed in the theme.The Settings switch.
In the app, open Settings and check that Enable the Listen button on product pages is on.The theme block.
It is a theme app block, so it renders only on the template it was added to, it works only on product pages, and shoppers only see the theme that is published. It does not carry across when you switch to a different theme. Re-add it after any theme change.
How to fix it
In Settings, click Add Listen button to my theme to open your theme editor on a product page, click Add block, choose Miko Listen Button under Apps, and click Save. If the plan is the blocker, upgrade from Plans in the app menu.
The feature reads text aloud using the browser’s own speech engine rather than generating audio files, so nothing needs to be uploaded or hosted, and available voices differ between browsers and devices.
