Thank you for your post!
When it comes to your conditional access policy are applying to the myapps portal, I believe this feature isn't supported as of now. As stated within this GitHub thread, "adding the myapps portal as a selectable app you could assign a Conditional Access policy to, is something you could open a product feedback item on, for the product team to review."
As of right now, the only cloud apps we have that are supported under conditional access policies can be found here - Microsoft cloud applications. If you enabled the Microsoft Azure Management cloud app, then the only sites that will require MFA are:
- Azure portal
- Azure Resource Manager provider
- Classic deployment model APIs
- Azure PowerShell
- Azure CLI
- Visual Studio subscriptions administrator portal
- Azure DevOps
- Azure Data Factory portal
If you have any other questions, please let me know.
Thank you for your time and patience throughout this issue.
