I understand "security though obscurity" and all that, but I just spent the last few hours trying to figure out why my avatar keeps randomly failing security checks every few weeks. The SDK tells me nothing, the game just says "Security checks failed", VRChat support sent me a canned response without even looking at my avatar. Meanwhile some random person in the Discord is like "oh yeah the uncompressed size is too big". If the game could have just TOLD me that it could have saved me HOURS of running around online trying to find an answer.
And this happens only on the quest version of just one of my hundreds of avatars, the only reason I even knew about it is because a fan told me they couldn't wear the avatar anymore. The first time I just re-uploaded it and it was fine for like a month so I figured it was just some glitch because I am given absolutely no information.
Please add a notification like the ones we get about impostors that tells creators when and why a security check failed so we can fix it. If you don't tell us, how are we ever supposed to know what to fix.
