Razer nommo pro V1 problem..

Hello, I have a problem with the bluetooth connection on my iphone 16 pro max.. Everything is paired but when I turn on the music the music does not play through the razer.. and on the razer control the bluetooth button flashes and does not light up like the others like when I have it selected via USB to Computer.. I did not find a single topic on the internet to solve this problem.. Could you please help me? The problem occurred when switching from an old phone to the iphone 12 pro max, everything worked as it should, only when changing the phone and downloading the application to the phone it no longer works.. I also tried it on my friend's iphone 11 pro and the same problem.. Thank you
