Only the wallet apps are affected though, it is same that their efforts are going to focused primarily toward institutional and enterprise custody services. Those businesses will continue operating normally.
I found some bounties and discussions about Cobo way back like 2019. But not sure if it is the same service.
In any case, if you have funds in their wallet, better moved it out before December 1.
