Events were flowing but suddenly stopped - Upstack Data

Likely cause: A recent theme update or theme switch disabled the Upstack app embed. Shopify resets app embeds when you publish a new theme. Fix:

Check whether you recently published a new theme or updated your existing theme. In Shopify admin, go to Online Store → Themes and note the active theme name.
Click Customize on the active theme, open App embeds, and re-enable the Upstack Data embed.
Click Save and test with an incognito window.
If you use a staging/draft theme, remember that app embeds must be enabled separately on each theme before publishing.
