I am trying to recover my Blockchain.info account.

I have the identifier. I have the password. I have the mnemonic seed given to me when I originally made the account.

Problem is, I enabled API IP whitelisting to an address that I no longer have access to. I have attempted to use the recovery seed in Electrum (not compatible), Mycelium (not compatible), and Blockchain.info (just gives me the identifier and password that I already have, then tells me my IP address isn't permitted access, because of the IP whitelisting)

What is the point of having a mnemonic recovery seed if it's useless for anything other than recovering on THEIR website?

Can I use this recovery seed anywhere else to recover these coins?

What am I missing here? Anyone have any ideas?

Thanks.
