Entra-enabled app crashing in Intune Work Profile but not in Private Profile

Question

A customer is experiencing an issue with an Entra-enabled iOS app in MDM using Microsoft Intune. The app crashes immediately upon initiating the Entra login when using a Work Profile. In contrast, it works fine with a Private Profile.

Another customer using a different MDM (Oracle Identity Manager) resolved a similar issue by setting the SSO key "disable_explicit_app_prompt" to zero instead of one. However, this workaround did not resolve the crash for the customer using MS Intune, as "disable_explicit_app_prompt" cannot be set to zero and defaults to "not configured."

According to the online documentation, when "disable_explicit_app_prompt" is not configured, its default value is "1." Can anyone confirm this? Additionally, why might the app only crash on the Work Profile?

Further details include:

• The app successfully uses Entra login when not managed by MDM.
• The app utilizes the MSAL library for authentication.
