thanks, i tried it and the address still didn't show up.

Try every derivation path you can choose (BIP44 examples):
The "External/Internal" option will choose if you want to display Normal addresses (0=external) or change addresses (1=change/internal).
The "Account" will choose which "account" you want to derive, you can set '2' or above.

But AFAIK, blockchain.com doesn't use change address derivation path so,
this might be a case of "upgraded wallet" and that address doesn't belong to your SEED. (I can't help you any further)

BTW, the "chat" from your reply (post#5) doesn't sound right, are you sure that it was blockchain.info's support that you're talking with?
