z_listaddresses list two z-addresses and when I check with z_getbalance both addresses have no balances.
z_gettotalbalance lists 1.00003450 balance.
zcash-cli listaddressgroupings lists two t-addresses both with balances that ends up to the total balance above.
In the user guide Home · zcash/zcash Wiki · GitHub I can see how to transfer funds between z-addresses.
Is it possible to transfer from t-addr to z-addr?
How can I see which z-addr is associated with which t-addr?
