It may be my imagination, but it seems like it frequently takes a longer time for the audio to come back after a commercial skip than it used to.
It doesn't actually need to be a commercial skip. Any skip forward or back can trigger it, but I most commonly notice it after a commercial skip. It probably happens following well less than half the skips.
Possibly related to a recent firmware update on my Bravia TV. But I haven't noticed any similar issues with other apps.
