I tried to spend my blockchain.info coins, sat a high fee but the transactions were not confirmed.
Then, I tried to move my private keys to electrum, but for some reason electrum wallet says: "No input found!". How can I move my blockchain.info funds?
Two questions:
1) did you export the private keys, or did you export an xprv? I have not used blockchain.info in ages, so i have no idear how you'd export your private keys
2) have you tried switching electrum hosts and tried a restart?
the reasons i ask these questions:
1) if you exported an xprv, the derivation path has to be correct... Otherwise you won't be able to derive the correct private keys, so the addresses created by the public keys created by the private keys derived with the wrong path would have no inputs
2) maybe you're connected to a lagging server (to switch: click on the green button on the right bottom corner and pick a different server)
