Cant see post install events using Appsflyer

Hi all,
Im using Appsflyer as my MMP.
i recently added Unity Ads as a partner and opened a campaign.
Unity is getting the installs correctly but when looking at the report builder i see no retained users.
In Appsflyer and in my DB im seeing the right numbers but it seems unity doesn’t get the post install events from Appsflyer.
Game ID is set correctly, and im sending the postback events as written in the documentation.
Does anyone encounter this issue and know how to resolve?
