IOS errors when a subscriber unpublishes

When a subscriber unpublishes I receive this error: null is not an object (evaluating ‘streamManagerVideo.video.parentNode.removeChild’). steamManagers.434

The issue seems to occur for subscribers which initially I subscribe with no element to attach it to e.g.

var subscriber = session.subscribe(event.stream);

If I then call create video element on that subscriber, and so can see the video in the dom, I still get the same error when that subscriber unpublishes.

Even if I do not attach a video to the dom, but rather just store the subscriber object to be appended to the dom later (I only want to show one video at a time on the screen), I still would like to be able to have the user publish and unpublish. Is this possible?

Yep, it should be possible. Probably you hit a bug. We will take a look in the following days.
