Confusion around UA, GA4 and Google ads remarketing Parameters

Hi,
I am using GTM4WP for a Woocommerce Store.
I have a Universal Analytics Property and have not upgraded to GA4 yet.
I have the remarketing Tag installed according to your tutorial:
https://gtm4wp.com/how-to-articles/how-to-setup-dynamic-remarketing-in-google-ads-adwords

So far, I had used the ecomm_ Parameters for the Google Ads remarketing tag.
Now, I have Upated the Plugin and the Tags, and instead of the ecomm_ parameters, google ads receives value, id, google_business_vertical and event from the tag.
My Ads guy says that I need to keep the ecomm_ parameters in order for remarketing to work, but I don’t think that’s the case.
He does not know if remarketing will work with the new parameters.

I have three questions:
1: Do I understand it correctly that value, id, google_business_vertical and event are GA4 parameters?
2: Does Google Ads automatically understand the switch to the new parameters without the need for me to change anything in Ads?
3: I have my Universal Analytics property set up as a data source in ads.
I get two errors:
“Issue: 100% of Product ID values received in the past day didn’t match your feed”
and
“Issue: 91% of audience source activity missing Product ID in the last day”
Do I need to upgrade my analytics property to GA4 now in order to work with the new remarketing tag parameters?

Thanks for any help.
