Reproducible in the demo app?

Yes

Reproduction steps

1. Play a DASH Live Manifest (a real Live Stream)
2. Create a MediaItem.LiveConfiguration.Builder() and call setTargetOffsetMs with 30_000
3. Apply via setLiveConfiguration on MediaItem.Builder
4. Observe live offset by polling Player#getCurrentLiveOffset
5. Run into an error (e.g. by disconnecting the device from the internet)
6. Re-establish connection
7. Hit Play button in sample app (which calls Player#prepare)
8. Observe live offset by polling Player#getCurrentLiveOffset

Expected result

1. In Step 4, the live offset is around 30_000
2. In Step 8, the live offset is around 8_000

Actual result

1. In Step 4, the live offset is around 30_000
2. In Step 8, the live offset is around 30_000 so it stays the same

In other words: The LiveConfiguration that was set when starting the player, should remain active, even after a "retry". From my observation it's still set but somehow ignored by the player.

I'll sent a URI via mail that can be used in the demo app by adding it to media.exolist.json
