Working with a client using Dynamics 365 for Phones with Dynamics CRM Online (2016 not updated to D365 yet)...
Previously, it prompted for MFA every time user logs in.
There was some issue with MFA Microsoft addressed at the end of December when they released the latest phones app update to Apple app store.
I thought it still prompted for MFA every time.
But since last week, it no longer prompts for MFA.
My client is assuming it changed from forms based authentication to use the oath token like other MS mobile apps. (So it will prompt for MFA credentials every 90 days!)
I can't find any supporting info/announcement from Microsoft.
Any thoughts?
