Problem with Consent Mode and Google Ads conversions only in Magento

I have a couple of clients on Google Ads who are using Magento 2, and I’m experiencing issues with the native Google Ads conversions for both of them (considering they have budgets of 2k/day and record dozens of purchases through the campaigns). After implementing Consent Mode, I basically can’t get Google Ads conversions to work anymore. I have several clients on various platforms where everything works correctly (Prestashop, WordPress, WooCommerce), but the only two on Magento don’t, and I’m forced to use GA4 conversions, which seem to work perfectly (even though they have the same triggers). They used to work before… since you see many sites on Magento, do you know if there are any known issues that I might have missed?

Could it be that the url_passthrough doesn’t work with the checkout (which cleans the URLs from the parameters) and therefore doesn’t work? The strange thing, however, is that GA4 works perfectly.

Anyone?

Thanks in advance
