GA4 and Raptive Ads show less Page views than Matomo

Using self hosted Matomo, running from a separate server, the tracking ID is implemented via the GA4 tag manager. We also have Raptive Ads installed. Most any day of the week, GA4 and Raptive agree to the exact number the amount of page views, Matomo is often nearly double. I’m trying to find out why and what the difference could be and how to rectify this. Honestly I’d obviously love if Raptive was agreeing with Matomo’s finding of traffic. Due to the fact that Raptive and GA4 agree on numbers, i’m kind of frustrated and have been tasked with finding what is causing the difference.
