Unfortunately keybase.io is effectively unmaintained since years. There are bugs that prevent updating the PGP keys:
https://github.com/keybase/keybase-issues/issues/2793#issuecomment-906017252
Please consider extending the keyoxide proof to not just keybase's API call for the PGP key, but also user bio, see e.g. my profile https://keybase.io/albron
Thanks for the consideration.
