Google Analytics Set-up & Shopify Products Link

Hello,

I have set up my google analytics, added my GA4 tag and am having issues getting my Shopify products to link through and show on Google. I just need expert help setting it up correctly. Bonus if you have skills in google ads too.

Have a bidget for a few hours work as I don't think it will take long, I just need the issue fixed.

Thanks,
Amelia
