Our application has native support for Stencil based themes. But it will also work on Blueprint based themes if you follow a few steps.
After the app installation finished, go to the App > Settings
menu and click on the Script installation
tab.
You need to copy the code snippet and insert it to the Storefront > Footer
scripts:
If your store uses a Stencil based theme you'll see other information under the Script installation
tab,
where you'll able to automatically set up the script code if it for some reason didn't install during app installation.
Just click the Reinstall the script
button and the app will insert its own code snippet into Script Manager
.
