GA4 data not available in Google Ads
We have been running GA4 and Google Ads on our website for a while now. However, the GA4 data appears not to be available in Google Ads even though the accounts are linked. For example, we can see 'All user' data in GA4, but the automatically imported GA4 audience 'All users' is not being filled (it does have some users, but that is probably from when we use UA). I have installed the GA4 tag through GTM, and it is working as GA4 data gets filled.
GA4: Linked account
GA4: All users
GAds: GA4 All users in Ads
I have cross checked all links, property codes etc and all do match with the corresponding account, but unfortunately the data is not being imported. Also, when I create a new audience in GA4, the data is not available in Google Ads. When I configure the Google Ads remarketing/conversion tag in our GTM, the audience does get filled.
Am I missing something?
