The latest update, which aimed to address reauthentication failures, has not improved user sentiment or stability. Android ratings declined by 0.9 stars following the release, and users continue to report issues with account access. The update is classified as having a negative impact due to the lack of observable stability gains.

Fixes an issue where reauthentication failed after Zscaler Client Connector was upgraded to version 4.2.0.173.

The latest update focuses on critical connectivity and authentication fixes for iOS. While the average rating rose from 2.05 to 3.67, the small sample size of three reviews limits the statistical weight of this improvement. The resolution of persistent network access failures provides a positive net impact on stability.

* Fixes an issue on iOS 26 where Zscaler Client Connector remained stuck in an authentication loop while authenticating through an SSO extension for several minutes before completing sign-in.

* Fixes an issue where devices connected to IPv6-only networks and in tenants without the IPv6 feature enabled for Zscaler Client Connector fell back to Zscaler Tunnel (Z-Tunnel) 1.0, because the QUIC drop policy wasn't applied.

* Fixes an issue where after a device reboot on a cellular-only network, traffic intermittently failed to route through the Zscaler Internet Access (ZIA) tunnel.

* Fixes an issue where Zscaler Client Connector displayed the message Invalid MDM Config, when Zscaler Digital Experience (ZDX) remained stuck in a connecting state due to an incorrect management device management (MDM) configuration.
