We recommend using Apple AirPods products or wired headphones when doing multitrack recordings. Other Bluetooth devices may work but are untested and may create a delay due to the latency of the wireless connection.
If are using Apple AirPods or wired headphones and still experiencing sync issues please submit a request for support from within the app by tapping the Settings icon in the upper left of the app, then tap “Report an Issue” and describe your issue.
