Cannot set up a recovery key
I am trying to set up a recovery key on my MacBook. I set it up and print out the key. I then try to do the final step and enter the key that has been provided. When I enter the key I printed out, I get a message that the key is wrong. I have double and triple checked that I entered the key correctly, but I still get the message that it is wrong. I tried setting up a key multiple times only to get the same result.
Any suggestions?
MacBook Pro 13″, macOS 11.6
