Its not a big deal. I was following your guide and copy the wrong text and when pasting it SN marked as an error. So I double check what was I copying.
It's easy to make mistakes. In step 2.2 you should copy your address@coinos.io and paste it on SN input field. That will be only for receiving sats from SN.
ignore the whateverusername@coinos.os is just a dummy account
