    I think the issue is a bit more severe than initial thought..., fixing all the scales to something higher than zero works but the problem is that using any Vector2 instead of Vector3 in scripts causes the z scale to be automatically 0 :(

    Any estimates when this could be fixed? We should stay with 5.6 because of this issue too.

    Hello, its now over 2 month and we still can't switch to new 2017.1 release due to the issues with the canvas in screen-space - camera mode and the event system not working. Is there any estimation when this bug will get prioritized for a release?
