GA4 internal promotion tracking

Hello,

We have installed the GA4 extension and it seems to be working OK however I have two issues:

1. No internal promotion events appear. When I look at events fired I see no view_promotion or select_promotion events. We have not altered our html and it was working fine with universal analytics (again WeltPixel addon). 

2. The add to cart event seems to be missing. It is tracking sales but without items being added to cart which does not make sense. We are using aheadWorks ajax add to cart (perhaps this is the reason?)

Any ideas how to fix those two issues?

Thanks,
Michael
