Headphones won't reconnect after using assistent

Firmware 2.1. 126
Pixel 4 XL Latest update as of 4/23/21

Everything works great except for the assistant:
Double tap, get a beep
Ask assistant (google) a question
Assistant answers.
I have tried double tapping and nothing. It never exits I the assistant, just beeps but no longer responds. Hit play button, nothing. Display on phone shoes audio app with the Pause symbol indicating it is playing, but it isn’t as the the time line does not move. if I hit the Pause/play on phone screen it starts playing through the headphones and I am back to where I was before the original double tap.

Does this work for anybody? I guess I don’t see how to exit the assistant once I have concluded my query.
