Unity 5.5.0f3 new splash screen not showing on iOS - is there a trick?

So I upgraded to Unity 5.5 mostly to take advantage of the new splash screen and this works great on Android but my iOS builds just show a flat grey-ish background and no splash screen while loading.

Is there a trick to get the splash screen to show on iOS?

My project was originally a 5.4.2f2 project that I upgraded (in case that’s relevant). I deleted the Library folder prior to opening with 5.5.0f3.

I really like the new splash screen - looks way more professional so I’d really like to take advantage of this!

Hints? Ideas?

why nobody answer this question. I have the same problem too.

Yeah I got some answers here: https://forum.unity3d.com/threads/5-5-released.443545/page-3#post-2878710 (read from that post on)
