Mailchannels: sender is not authorized

I'm getting:

0    "Failed to send email: 550 5.7.1 This sender is not authorized to send from my-site.com. See https://bit.ly/domain-lockdown. cfid=my-site-v3.pages.dev"

0    "Failed to send email: 550 5.7.1 This sender is not authorized to send from my-site.com. See https://bit.ly/domain-lockdown. cfid=my-site-v3.pages.dev"

I have a TXT record with:

name:

_mailchannels

_mailchannels

value:

=mc1 cfid=my-site-v3.pages.dev

=mc1 cfid=my-site-v3.pages.dev

(copied as is from error message)

Do I need to just wait for DNS to catch up, or am I missing something?
