@pablophg Please test the changes using the pre-release and let me know if everything works so we can merge this.

I tested the changes and the behaviour is as expected on iPad:

• No enableMultitaskingCameraAccess (or manually set to false):

• enableMultitaskingCameraAccess set to true:

This works as expected for this feature.

Now, there's one corner case, and in any case, I think should be implemented as a separate feature:

• When on iPad OS 26, if an iPhone app (no iPad support) is launched wiithin an iPad, it launches in windowed mode. If such app only supports upright portrait mode on iPhone, when opening it on an iPad, if the iPad is on landscape, the camera feed appears to be rotated (see my second screenshot). This is probably overlooked by Apple.

In my app I solve this by rotating the camera feed to align with iPads oorientation even if my app only supports one orientation, due to how Apple handles opening this iPhone-only app on iPads. It is a very specific case and I'd say not related directly to this feature.

To cover this corner case, a feature that allows auto-rotating the view, could be implemented appart from this one. What do you think? Or you think it should be part of this same version?

I also think it's not related to this issue. Thank you for testing!
