Thanks for your report!
That's a bug in
HlsInterstitialsAdsLoader. I can repro this with a unit tests and a sample stream with the player when using asset lists. We'll provide a fix for this.When the timeline is updated and the position is before a mid roll, the content position needs to be resolved for an ad start position before being used to select the next asset list to be fetched. This way, the initial selection when joining the stream is behaving as for a seek, which is the correct behavior for VOD and live.
