My wallet has enough funds to make the 3 transactions above, there's no ongoing pending transactions before I made any of the 3 payments. I don't understand why the 'Unconfirmed Parent' occurred
An input that you used is unconfirmed. Check the transaction details and you'll realize that if you check the inputs of the transactions with unconfirmed parent, at least one of the input is unconfirmed.
I open the details for all 3 transactions, each has inputs and outputs
There's one output in transaction 3 (Unconfirmed) is the same as one input in transaction 1(Unconfirmed Parent)
There's one output in transaction 1 (Unconfirmed Parent) is the same as one input in transaction 2(Unconfirmed Parent)
What are the relationship of these 3 transactions ?
