Hello @joshuabecke
Welcome to the Auth0 Community!
I am sorry about the late reply to your inquiry!
The Remember browser for 30 days prompt is not available during enrollment, it appears to be expected behaviour. However, there is an update which will allow members to update MFA UI for Universal Login using the ACUL SDK.
Otherwise, I would advise you to submit a pot on our Feedback forum, feel free to let me know if you have any other questions!
Kind Regards,
Nik
