Blockstack Mac App won't recover keychain

I updated my mac to High Sierra recently, and the blockstack app reverted back to its initial state. When I try to recover the keychain (by typing in the phrase and password) nothing happens when I hit the button to recover. The only way I can access the app is through the limited web client; I tried deleting blockstack and reinstalling, but the same issue persists.

Another question:
Is it supposed to log-off as soon as my computer goes to stand-by, or I restart my computer?
I hate having that huge password at hand at all times.
