My transaction has been unconfirmed for more than a week. I had a normal transaction fee (not low). The amount of the transaction was not small >0.5btc. The inputs were not unconfirmed outputs.
The transaction came from a Mycelium wallet to a Bittrex wallet. The Mycelium wallet has no option to increase the fee. The Bittrex wallet has no way to try to spend the unconfirmed outputs to create a CPFP transaction.
Any ideas how I can fix this?
This is a complementary question to Why is my transaction not getting confirmed and what can I do about it? which answers the question's broader implications and proposes mitigation mostly focused on Bitcoin Core.
