Disabling Authentication MFE in Olive with tutor

I’m working on upgrading our installation to Olive. I’m currently running tutor version 15.3.7.

I want to disable to Authentication MFE for this release. I do plan on running the Learning MFE.

I followed the instructions from the readme here: GitHub - overhangio/tutor-mfe at v15.0.6

tutor config save --set MFE_ACCOUNT_MFE_APP=null

And confirmed the change is in my config.yml file:

MFE_ACCOUNT_MFE_APP: null
MFE_LEARNING_MFE_APP:
  name: learning
  port: 2000
  repository: https://URL_TO_REPO
  version: main

I rebuilt all the images with --no-cache set and reran in both dev and local mode.

The Sign In button always redirects to http://apps.local.overhang.io:1999/authn/login?next=%2F

I also turned off the following waffle flag:
account.redirect_to_microfrontend

And set the following in the site configuration:

{
    "ENABLE_PROFILE_MICROFRONTEND": false,
    "ENABLE_ACCOUNT_MICROFRONTEND": false
}

What am I missing?

Thanks in advance!

You are disabling the account MFE, but what you want is to disable the authn MFE. The former is used to edit details about your account while the latter is used for login and registration.
