Google Tag Manager - Conversion Tag Not Working

I'm losing my mind trying to track conversions in Squarespace Commerce, this should be simple. I just want to be able to track conversions in Adwords.

I have the main code on all pages, then the event snippet on the order confirmation page.

I've used the google tag management assistant and gone through checkout a bunch of times, the Purchase doesn't trigger. I've looked on the order confirmation page and you can see the tag is there.

What am I missing here?

Unfortunately, I disagree that conversion tracking is only confirmed setup after getting a conversion. I burned through money because it wasn't tracking conversions.

I've added the code, no idea what is wrong here. Really frustrated with Squarespace as they wont provide any support for 3rd party integrations, even as basic as conversion tracking.

What other options? I can't stay on squarespace if it doesn't support conversion tracking.

Same problem, squarespace really gives a sh** about customers, especially when it's about third party stuff. Tried this for half a year now and CC is not helpful at all. I'll set up my page completely new on wordpress and save a lot of money as well. 

btw the other bugs such as importing meta data from pictures is still not working, after YEARS

They just don't care, take the extra effort and go to another hoster that actually cares, stop wasting your money
