Salesforce Field Service and Salesforce Mobile Apps Report Older iOS Version on Intune and Other Mobile Device Management (MDM) Tools

The Salesforce and Salesforce Field Service apps on iOS and iPadOS may incorrectly report the operating system (OS) version to Microsoft Azure, causing a mismatch with the browser version and impacting Mobile Device Management (MDM) security policies.

Starting with iOS 26, Apple froze the User-Agent (UA) string — the text that apps send to servers to identify the device's OS version. Instead of reporting the actual iOS version, the UA string reports a static version (for example, iOS 18.6). Apple introduced this change primarily to protect user privacy by reducing device fingerprinting.

As a result, MDM tools such as Microsoft Azure Conditional Access that rely on the UA string to determine OS version will show an outdated version, even when the device is running a newer iOS release.

Lösung

Because Apple has frozen the UA string on iOS 26 and later for privacy reasons, User-Agent-based OS version strings are no longer a reliable indicator of the actual operating system version on iOS devices.

    1. The User-Agent (UA) string is no longer a dependable indicator of the operating system version on iOS 26 and later. Microsoft Azure reflects the version information reported by the device itself, which may be intentionally obscured to protect user privacy.

    2. It is recommended to update Azure Conditional Access policies to use Microsoft Intune or Device Compliance state for compliance evaluation, rather than relying on Browser or OS Version strings. This ensures accurate and reliable policy enforcement, as UA-based OS version strings cannot be trusted on iOS 26 and later.
