This is wrong. It does stake in hybrid. We are aware some people have issues and we are working on a solution but don't go into details if you don't know what's going on.
Hybrid does have the entire blockchain.
Nope, because if you switch to classic mode it redownloads the entire blockchain from scratch.
Different Blockchains data files are being used 1 for classic and 1 for hybrid.
Which is why hybrid will never work for staking and will cause future problems.
