I had a problem and it has been resolved after submitting my documents. I don't know what trigger it also but probably I am exception but generally if you expect all users to KYC, I don't think the casino will manage to have a lot of wager volume in my opinion
Are you still new on crypto casino gaming? KYC is inevitable in every casino with gambling license because it’s a requirements mandated by the AML policy set by their license provider. It’s a requirement to operate legally to all the supported country.
I’m not sure how often you play in the casino but you can trigger KYC if you show some sign that potentially violates the ToS such as game pattern, withdrawal/deposit pattern, IP connection and so on. Your best shot to play a no KYC games is on unregulated casino but you risking your money in there because they can always run without a trace.
