Site speed issues - unknown resource - intl.TelInput.js

Hi there, our site speed on Gtmetrix seems to have doubled, which is very concerning. The main suggestion it's always fed back is related to this :

The following resources have identical contents, but are served from different URLs. Serve these resources from a consistent URL to save 1 request(s) and 66.7KiB.

I have no idea what this .js file is — can we delete it somehow? Would you be able to take a look at the GTMetrix report and make any suggestions for us? We have tried consulting a couple of freelancers to help but they weren't much use. This is really important for us to fix - our conversion rate has been below 1% even though we have a good product and passionate customers; I believe if we can finally fix the site speed issues we will have a better chance at success on Shopify.

Apps can add their own javascript files onto your site. Consider looking through all apps that have access to edit your themes or add their own scripts.

Hi @Charlie_McEvoy 

The intTellInput.js code is probably automatically added by Back In Stock app. I have client store with the same behavior.
