Full Space Immersion auto fade in outside of 1.5 meter from the origin

After updating the ALVR AVP app from the AppStore it is not possible to have the Full Space immersion mode outside of 1.5 meter from the origin. Earlier the passthrough was automatically ca. 40% faded in during the movement and afterwards faded out.

Now if you go outside of the 1.5 meter origin the passthrough is 100% visible. And its only possible to enable the Full Space Immersion with a long click of the Digital Crown. I tried all possible settings. Nothing worked for me. And actually I don't even remember how I enabled it with the version before. May be it was a bug of the visionOS?

Is there any information on the topic?

Thank you one more time for this amazing software!!!
