This is likely because it's too expensive for mobile. Try turning off some features such as PBR and probes, would probably make it work again.

Thanks for finding this out! This has been an issue for a very long time, and nobody had ever really found a consistent way to get Unity to download the correct one. I presume it works now?

Turned out to be a bit trickier than I anticipated, and got delayed for various reasons! I can look into this again for the next update.

SF doesn't support beta versions I'm afraid. The next update will be for 5.6, and after that it'll probably start to target Unity 2017.

One thing I noticed that is likely the issue - depth blend only works when lighting preview is on. If it's off, it stops working. In addition, materials now have a render order as well, which might be the culprit.

This is a known issue, and will be fixed in the next version. Apologies for the inconvenience!

Currently there's no way to access probe data and manipulate it specifically in SF, but it might come in a future update.

Sounds like a Unity bug to me. Have you been able to find out something more since?
