The problem is, when i go to "Blockchain wallet - settings - addresses" i see no address there, the following message show up
"Imported addresses Not supported by your recovery phrase. Transfer to a portfolio to secure funds."
It looks like you imported an address to your blockchain wallet. Settings - addresses - imported addresses - scroll down - there have to be an address or addresses. Click more options, if you imported an address using private keys properly then you will see private key and transfer option.
Only after writing down the private keys transfer your funds to blockchain wallet.If an address is watch only then you imported an address without private keys.
Imported addresses are not backed up by the wallet recovery phrase. We strongly recommend you to transfer funds from imported addresses into this wallet by going to Settings -> Addresses -> Imported Addresses -> Transfer All.
