I do get sales, and no errors but checking data is almost impossible. Today out of 6 sales I only see 2 in FB ads manager. While UTM's show that all 6 came from Fb ads.
I assume if pixel sees only 2 sales then it doesn't take other 4 into the optimization.
I also checked operating system this sales came in, and Android sales also not being counted.
I also got this error only today. Even though I had customer purchases and the purchase event detected them, I am not able to view this data in my ad campaign and it's difficult to attribute the purchases to a specific ad set!
I don't know if this is related to the error but I'm assuming it is.
is there an update on this issue?
