Back in Stock not working with Langify App in Shopify

Hi there,

I’ve integrated the Back in Stock Snippet following the documentation (https://help.klaviyo.com/hc/en-us/articles/360001895651-How-to-Install-Back-in-Stock-for-Shopify) and it works like a charm (very easy, thanks ;) ) :

BUT: We’re using the App Langify in our Shopify store for the second language (German) and switching language means that the ISO code “/de/” is put into the URL for all translated pages. Unfortunately in this setting this creates a problem, the Console log returns “deny” and the Back in Stock button does not show:

I couldn’t find anything in the Forum so far, any hint and help is greatly appreciated!

Thanks
Stephan
