Kevin,
Good call on the Save Changes under the account. It claimed that the token had expired, so it made me refresh the login and confirm 2FA. All set and emails are now working.
Thank you so much. Cannot express how helpful that was!
Further into the API 403 error, is the banlist the root cause of the OP topic?
Or is it related to bad email/ui accounts? I'm just interested in the error and further diagnosing. Thank you again.
