I had the same error, but whether I add the code
add_filter( 'option_rop_first_install_version', '__return_false' );
or not, the button “Use your own keys” is always there.
With me, after following the steps, I got this error

After starting all over again, Deactivating the plugin and Purging all caches, I managed to eliminate the errors. In 25 minutes, I will know whether it works this time. Yesterday, the fix only worked for one post, and after that, I got the 429 error again.
