There’s no avoiding the PSoD, it’s intended to be there as that would usually be when you’re seeing pre-roll ads but because ads are not supported in the Embed player you have to wait through that PSoD instead to prevent the Embed player being misused as a way to avoid ads.
It may just be a coincidence that the PSoD didn’t play while viewed on a site, or it may have been playing a channel that wouldn’t have ads displayed, which may impact if PSoD’s are displayed in Embeds.
