I have been in contact with bit.store‘s support today and got my answer 1,5 hours after sending my message. So support seems to get better.
Btw.: Theyr physical card does not support 3dSecure either. Just like the virtual card.
Their physical card also have bigger limits but you have to perform verification to receive it.
Only no-kyc card I know that has 3ds support can be found on Stealths.net website, but this card is for single-use only.
