Thank you for taking the time to read this.
I'm a Japanese engineer utilizing Facebook's Conversion API to provide services. Since around May 7th, 2024, Japan time, we've received reports from clients that while conversions are being recorded in the Event Manager, they are not appearing in the Advertisement Manager.
As there have been no changes made to our program, it seems unlikely to be a bug on our end. However, if anyone is aware of similar occurrences around the same time and has any insights or solutions, I'd greatly appreciate hearing them!
I've checked the recently updated documentation, and the fbc format appears to be in line with what's stated. If there's any additional information I can provide, please let me know.
