I'm having a problem sending external requests on my Unity Play. I originally found this out for leaderboards because my UGS leaderboard stopped working out of nowhere so I built a test API hosted on vercel and it's not working either. I posted on Unity's forum but I can't seem to get any answers. Can anyone help? https://discussions.unity.com/t/unity-play-csp-errors-when-fetching-from-external-api/1702019
