SEB Screen Proctoring shows blank screens on iOS 26

[a-camacho]

Describe the bug
After updating two ipads (iPad Pro M2, iPad Air) to iPadOS 26, and one MacOS device, we observed that screen proctoring does not work anymore correctly on iPad, but still works correctly on MacOS.

The problem is that SEB interface is captured but the content of the webpage (Moodle LMS, other website) shows completely blank in SEB Server.

To Reproduce
Steps to reproduce the behavior:

1. Update to iPad OS 26
2. Start exam with proctoring
3. Watch recording and webpage content (see images bellow)

Expected behavior
Webpage content should be visible in SEB Server recording.

Screenshots

Version Information
Please complete the following information:

• OS: MacOS 26 - iPadOS 26
• SEB Version: 3.6

That's bad news, Apple must have changed the API which I used to capture the screen shots to no longer work in the AAC Assessment Mode.

I submitted a feature request in the summer to provide an API to capture the full screen (including PDFs etc.) for the assessment app while in AAC. Until they provide such an API, no screen proctoring will be possible with secure exams on iPads.

It works with iPadOS 26.1 developer beta 1. Either Apple realized that there is a bug in iPadOS 26 or they didn't merge all changes from the final release build of iPadOS 26 into the beta of 26.1. I think screen proctoring worked with betas of iPadOS 26, but I confirmed that it doesn't work with the final release version.

Anyways, I will ask them what the status about this and my feature request is.

At least on macOS 26.1, a new property for the AAC Assessment Mode configuration was introduced which is undocumented, but called "allowsScreenshots". That could be related to my feature request, maybe it will allow to use screen proctoring with AAC and permitted additional applications on macOS 26.1, which would be great.

Maybe this new setting shows that they also allowed the assessment app to take screen shots on iOS 26.1, after blocking them in iOS 26.0. I will try to clarify this.
