How can I remove unnecessary Google tags from my ecommerce site?

[plfunkymusic]

Whilst analysing our Shopify site speed using PageSpeed Insights I noticed there is javascript for 3 google tags being loaded.  

The first is our G4A.  The last is the old AW tag which I'd like to now remove, but don't know how.  Any ideas?

And finally, does anyone have any idea what the middle tag is and how to remove it?

Many thanks!

Hello @plfunkymusic,

I can see there is a three Google tag scripts loading on the site. but that may be a third-party app's Google tag manager script. so we can't handle it from our side. 

If you have added a Google tag manager script so we can handle it. so just let me know which script we have added.

Ok, thanks.  I'll try to find out where that's coming from.
