I want to use the Partybox for karaoke with Apple Music. So I connected my iPhone to the Partybox via Bluetooth, everything works perfectly. However, when I now connect the iPhone to the TV via screen sync (so that I can see the text on the TV), it interrupts my BT connection to the Partybox. Via Android / Spotify it works without any problems. Does anyone have a tip, or does Apple generally not allow two BT receivers to be connected?
