Nine times out of ten the app embed is switched off. Open the app — the setup checklist reads your live theme and tells you honestly whether it is on. After that, check the popup is not simply hidden from you: it stays away for a while after you close it, and hides from logged-in customers unless you say otherwise.
Open the app and look at the last signups. If they are listed there, the customers exist in Shopify too — search your customer list for the address rather than the masked version.
The app shows a code; it never creates one. Pick an existing discount from the list in the Discount section, and check it is still active in Shopify.
Tell us your store domain and roughly when it happened, and we will look at what the app recorded. Email support@eversogoodapps.com.
