Yesterday i was using zcash4win for the first time. So i’ve maid a transaction and everything was ok, than i’ve made another transaction to the same address and the amount of zec’s moved from my wallet by did not come to the destination address. In my wallet the transaction is marked as unconfirmed. After that i made a third transaction to the same address and it is confirmed, but second transaction is not confirmed until now - 12 hours passed.
What should i do?
