This is a really excellent app!
I was trying to figure out how to put in a code in my store for the GDPR update and wasted at least 2 hours of my time trying to figure out. Finally after searching around the internet and shopify, I found this app which is very reasonably priced and was super easy to use.
The developer responded quickly when I thought it had stopped working and was able to fix it right away. Thank you very much! Highly recommended!
Works perfectly! I used this to add hreflang tags to each of my pages, and I'm sure I'll find even more uses for it. The developer is super responsive too- Thank you!
