Airpods PRO, on multiple devices?! how come only a single connection?

I did read in the specification that it can hold up to 5 simultaneous connections, that was one of the major buying points together with noise reduction, just as I have on bose qc35.... and I though for this price it would be the same for this compact earphones. BUT!!!!! I connected Mac book pro and a an android OnePlus 6T, AND - Airpods PRO disconnect from the other device, when I connect either one!!!!!!

Am I doing something wrong or would I really need to tolerate a manual re-connection every time I need switch between devices? Like when you get off a video conf on a notebook and a phone call comes in? Thats a significant issue over which I will return the product even.
