Hi @RoseLane, welcome to the community with your first post!
So a few things that can be happening here:
- Shopify Theme Popups: For some Shopify Themes, they have a built-in popup feature as part of the Theme. You can sometimes find it in the Theme editor. But because this various a lot from one theme to another, it is entirely up to the Theme developer/publisher to include that as part of their Theme.
- 3rd Party Popups: Are you using a third party popup tool? If so, you may need to migrate the integration code or app to your new theme.
- Enabled Klaviyo App Embed in Shopify: If you are using Klaviyo Signup Forms, and switched to a new Theme, make sure the Klaviyo App Embed is enabled. You can follow the instructions here: How to enable onsite tracking for Shopify : Enabling the Klaviyo app embed in Shopify
If you were using your previous Shopify Theme’s built-in popup feature, I recommend you use the Klaviyo Signup Forms instead. Not only will you be able to quickly build Popups (and other email capture forms like Fly-outs, Embeds, and Full Screen Email Captures), it also lets you do advance targeting options, multi-step forms, and A/B testing and much more!
Hope this helps, and let me know!
