The app embed that shows your Coming Soon page is attached to one specific theme — the one that was published when you turned it on. Publish a different theme and the new one has no embed, so your page stops appearing and visitors go straight to your storefront.
Nothing is lost. Your templates, settings, password, and allowlist all live in the app and are untouched. You only need to switch the embed on again in the new theme.
Re-enable it on the new theme
- Go to Online Store → Themes.
- On your newly published theme, click Customize.
- In the left sidebar, click the App embeds icon (a jigsaw puzzle piece).
- Toggle Coming Soon on.
- Click Save.
Duplicating a theme
Duplicating a theme copies its app embed settings, so a duplicate of a theme that had the embed on will have it on too. It is still worth checking after you publish the copy — a theme duplicated before you set the app up will not have it.
Trying a theme without exposing the store
If you are auditioning a new theme and do not want a window where the storefront is public:
- Turn the embed on in the unpublished theme first — open Customize on it from Online Store → Themes, enable Coming Soon, and save.
- Then publish the theme.
The embed is already in place, so there is no gap.
