Hello, I made a transaction on 9th Dec in my blockchain wallet and it is still pending.
https://blockchain.info/tx/85cf8b06772eac3cd92891acccb1e4e29847c3fd75e28456224d33a41e52fdae

I looked at blockcypher and it did not find any transaction with this ID, then I looked at https://btc.com/85cf8b06772eac3cd92891acccb1e4e29847c3fd75e28456224d33a41e52fdae and it says Removed / DoubleSpending

What happened? Is the fee too low or the transaction was removed?
