maybe the third party forgot about it?
you can ask for manual KYC verification through support, is that possible?
That's what I thought, especially since I checked the license and wasn't familiar with it. Generally my KYC works if license by Curaçao
There is also no way for manual KYC that's why they suggest to ignore KYC level2. I consider KYC not as a whale player but as a long term player
who knows this casino might offer something that makes me comfortable to keep playing or at least i have luck here

In the meantime, just ignore what the support suggests as there is no other way to do KYC right now.
Yes maybe because this is your caution in the future fear of problems so it's better to be more careful because if you win tens of thousands of dollars at any casino it is common to be asked for KYC.
So just enjoy yourself... just in case you don't have any problems in the future.
