Reproducible in the demo app?

Yes

Reproduction steps

Very coarse steps, happy to provide more detail if needed:

• Extend sample to use lib-exoplayer-ima extension without an adViewGroup in order to use createAudioAdDisplayContainer
• schedule client side skippable ad, e.g. https://pubads.g.doubleclick.net/gampad/ads?iu=/21775744923/external/single_preroll_skippable&sz=640x480&ciu_szs=300x250%2C728x90&gdfp_req=1&output=vast&unviewed_position_start=1&env=vp&impl=s&correlator=
• play the ad until it is in skippable state (5 seconds for the sample tag)
• call skipAd

Expected result

The ad should be skipped. The documentation on skipAd states that this should only be used for audio only ads.

https://github.com/androidx/media/blob/f6fe90f30ba022c7e04e14a3dc5c28c568a4d1e2/libraries/exoplayer_ima/src/main/java/androidx/media3/exoplayer/ima/ImaAdsLoader.java#L505-L510

In the past this also worked for non-audio only ads but given the documentation I guess it's intended that it does not work if a view is present.

The root cause for this behaviour change is a change on IMA side, see (1, 2) for reference.

Actual result

Ad does not skip

Media

Not dependent on main content, as skippable ad, https://pubads.g.doubleclick.net/gampad/ads?iu=/21775744923/external/single_preroll_skippable&sz=640x480&ciu_szs=300x250%2C728x90&gdfp_req=1&output=vast&unviewed_position_start=1&env=vp&impl=s&correlator= can be used.
