We previously reported three issues affecting devices running iOS/iPadOS 26.1:
-
Jamf Trust App configured with ODCF in Hidden-App Mode Results in Connectivity Loss
-
Update Process of Jamf Trust App Configured with ODCF May Hang Resulting in Connectivity Loss
-
Jamf Trust App configured with Zero Trust Network Access (ZTNA) in Hidden-App Mode Results in Resources Behind ZTNA to be Unavailable.
We are continuing to work closely with Apple, who has identified and resolved the underlying root cause. A permanent fix will be included in an upcoming iOS/iPadOS release.
The behavior can occur with any on-device content filter or VPN deployed on iOS/iPadOS 26.1, across multiple MDM environments when used alongside Screen Time restrictions, App Usage controls, or Kiosk/Single App Mode.
The following issues remain relevant until the upcoming iOS/iPadOS update becomes available:
1. Jamf Trust App Configured with ODCF in Hidden-App Mode Results in Connectivity Loss
When the Jamf Trust app configured with ODCF (or alternative ODCF app) is put into hidden-app mode, the device loses internet connectivity.
Conditions to trigger the issue (all must apply):
-
Jamf Trust is hidden via Kiosk Mode, App Usage configurations, Allowed Content Rating, or Screen Time restrictions.
Outcome:
2. App Updates May Cause Connectivity Loss for On-Device Content Filters
An intermittent issue may cause ODCF-based filtering apps, such as Jamf Trust, to hang during the update process, which can result in a loss of internet connectivity.
Conditions to trigger the issue (all must apply):
Outcome:
Note: This issue is intermittent. Many updates complete successfully even when all conditions are present.
3. Zero Trust Network Access (ZTNA) Functionality Is Affected if Jamf Trust is put into Hidden-App Mode
This issue impacts devices using ZTNA when the associated filtering app (Jamf Trust or other ODCF tools) is hidden or restricted.
Conditions to trigger the issue (all must apply):
Outcome:
Note: Behavior may vary. Some devices disconnect immediately when the filtering app is hidden and reconnect when it is visible again.
Updated Guidance
Apple has confirmed that the underlying issue has been identified and resolved, and a fix will be included in an upcoming iOS/iPadOS release. Until that update becomes broadly available, we recommend the following steps for any environment using on-device content filtering solutions:
If you are using another MDM provider or a third-party ODCF solution, we recommend working directly with that vendor for platform-specific guidance and update deferral instructions.
These recommendations apply across all MDM platforms and all on-device content filtering vendors.
