Revenuecat and Facebook ads integration seems to be working properly, events manager is collecting data for trial and subscribe events. However when targeting Subscribe event in a campaign (IOS 14.5+) the results are showing low to 0 subscriptions, while having a big number of trials in that campaign (campaign has been running for over a week now with no subscriptions which is very odd considering the optimization goal is the subscribe event). Wondering if anyone else faced a similar issue with event targeting?
