@abdullahwaheed @Syed-Ali-Abbas-Zaidi @Mashal-m Do you folks remember why this needed to be reverted?

@kdmccormick looking at NewRelic data for this deployment time, I see a spike in errors of the following:

builtins:ModuleNotFoundError
[prod-edx-edxapp-lms]
Error message: No module named 'openedx.core.djangoapps.user_api.accounts.toggles'

This error spike set off what looks like multiple alerts, which undoubtedly triggered the revert action. Sorry, but our NR data retention does not allow me to see more details about the error than what I pasted above.

I was able to dig this up from the corresponding Slack discussion:

actually it was failing to find module in django template, so it was causing a server error (500)

@abdullahwaheed Do you know what template it was?

I see a reference to in openedx.core.djangoapps.user_api.accounts.toggles in lms/templates/header/user_dropdown.html, but the PR removes that reference, so that shouldn't be the problem.

@kdmccormick, This same toggle is being used in edx-themes [ref], this was the reason why this PR got reverted. This toggle was not removed from edx-themes which caused the errors.

We also have this PR ready to remove this reference.

Also while digging into the issue, we found out that we need to handle all the legacy redirects of the profile and account page to redirect to the profile and account MFE instead. This PR can't go in until all the redirects are handled otherwise MFEs will break. FedBom started to create the PRs to handle the redirects but I don't know if FedBom managed to create all the PRs, @abdullahwaheed will have better knowledge about it.

Below are the PRs we created in profile and account MFE to handle the legacy redirects.
