Crossfade issues. Skipping a little and making a "gurgle" sound between the song transition

The problem seemed to happen only after I updated my ipad software a week ago. It seems to be an output issue. On automix when the song crossfades over, it has a glitchy sound and a gap in output. It seems to be related to running it as split output. Any help you can give would be most appreciated. Im a musician who “dj’s” between the sets and it really killed my gig last night.
