First tried to convert Piv to zPiv (clicked Mint Zerocoin)
That sum disappeared from the Wallet all together. In recent transactions I can see "send to zPiv Accumulator"
Will come back from that Accumulator. Or not?
No. There are lost of cases like yours. You lost your money. They have slack support channel.
They can give advice.
But I don't know successful stories.
I lost my pivs and don't hope to get it recovered.
On some wallet copies I have only "sent to zpiv accumulator".
On another "Orthan block. Generated but not accepted".
I don't know which copy is better.
Anyway, don't know what can be done with it.
