I haven't touched ReportPlayer code in a number of months, but I noticed in our PlayFab Event History page, the player_reported_as_abusive JSON always has a comment of null now.
It used to show the actual report comment.
In my code, I log the following:
[Log ] 29500 30.736: FairPlay: Received RequestReportPlayer user 47D83C3F26B5F202 from player 1 with category Griefing and comment: [GameID:ABC123][Time: 29503][Intentionally lost the game]: feeder
[Pass] 29600 30.838: Report went through successfully!
I'm confident that I am passing in a comment when I report the player. The comment is "[GameID:ABC123][Time: 29503][Intentionally lost the game]: feeder"
Is this comment too long or does it contain some invalid characters?
I know the report goes through successfully both due to my log as well as being able to see it in the Event History:
