Potential disruptions for mobile app users

We strive to offer a trouble-free, seamless experience for xMatters users wherever and whenever we can but sometimes things happen that are outside our control. This is, unfortunately, one of those times. 

Android App Certificate Transparency

  • Affects: Android
  • Impact: Automatic log out and forced version upgrade


On June 7, 2023 Google will be removing a URL that the xMatters Android app uses for its Certificate Transparency feature.  To ensure there is no gap in compliancy, we released an update to the feature in a patch for the current version of the Android app (3.19.1). The 3.20 release, which is currently being rolled out to users in a phased approach, will also include this change.

All versions of the Android mobile app from 3.19.1 and later are protected from this disruption. 

The disruption will occur for anyone still using an older version of the app on June 7. Those users will be logged out of all their accounts in the app and be forced to upgrade to at least version 3.20 before they can log in again.

To prevent any interruptions, be sure to keep your Android app up-to-date, and upgrade to version 3.19.1 or later before June 7.

QR Code Security Upgrades

  • Affects: Android and iOS
  • Impact: Older versions of the xMatters apps will not be able to use the QR code login feature


To help ensure that we're always using the best and most current security protocols, we're updating the encryption mode used for the mobile app QR code login process. Once the process is complete, older versions of the apps will not be able to login via a QR code (though they can still login using their username and password or SAML). 

We're confident this will affect very few users, largely because we have a high rate of adoption for the latest versions of both the Android and iOS apps (and we've also had a warning message about this issue on the QR code login page in the UI for the past couple of months). 

Again, to prevent any potential problems, be sure to keep your app up-to-date and upgrade to the latest version as soon as you get the chance. 

If you have any questions, please contact xMatters Support.

    Hi Kevin

    We tend to just encourage people to always upgrade their apps to the latest version as a best practice approach.

    But if you need specific versions, the new encryption mode has been supported on all releases since version 3.17 on Android and version 4.20 for iOS.
