The problem is we have an issue with FAS and CBA in our Tenant, where when we enable it, it will enforce Cert-Authentication for every user with Citrix access (so they have it as their top option, as it counts as more secure and it will default choose the most secure option in our Entra tenant). Also when reseting their MFA method, they also need a cert we don't have, so we need to give them a TAP for it to work.
The only workaround for this we found is, enabling CBA but "disabling" the option to log in like that over Conditional Access policies, but we have over 20 Conditional Access policies, which we would have to change from "Require MFA" to "Require Authentication Strength" to achieve this 😄
