Unity Ads 2.0.5 on iOS, doesn't play video ad then shows static end screen

Monetization & Growth Unity Ads

Hi, I upgraded Unity Ads to the latest version (2.0.5) from the Asset Store.
On iOS 10, iPhone 6, the video ad shows ‘Buffering’ for about three seconds (with spinning arrows), and the message ‘This video ends in 30 seconds’… , it doesn’t start playing at all, then it instantly skips to the static end screen.
When closed, the reward is not triggered (ShowResult.Finished isn’t called).

Same thing whether in Test mode or not.
Unity version is 5.4.2f2.
Works properly with iOS 9.

Here are logs from Xcode:

I/UnityAds: +[UADSApiSdk WebViewExposed_logInfo:callback:] (line:57) :: Unity Ads event: sending start event to https://adserver.unityads.unity3d.com/mobile/gamers/…/[ID]

It seems that it was only happening on iOS 10.0.1. After updating to iOS 10.1.1, it’s now working fine.
Thanks.
