Bluetooth sharing

I was disappointed to learn from a Bose advisor today that I can’t share a Bluetooth connection from my iPhone to two Bose devices.

Namely my new Tempo frames and my Soundsport Bluetooth ear buds at the same time.

anbody know if there is a workaround this problem?

I have also found since buying my Bose Tempo Frames three days ago that if my Samsung smart watch is on the frames start then switch off. Also when my phone connects to my car Bluetooth the frames shut down. This is not good
