Hi.

A speed report said that this, among other things, is slowing my site:

Amazon Web Services:

I found it in theme.liquid but, would it be safe to remove it?

I have removed a couple of other scripts from old apps but I am not sure here.

Thanks in advance

Hi @PeruMiski

If you’re no longer using the Last Second Coupon or Quick Announcement Bar app, then yes, it should be safe to remove this script from your theme.liquid. However, before deleting it, check if any announcement bars or coupon pop-ups disappear from your site
