ATC Volume

Device: iPhone 14
Operating system: iOS 17.0.3

I am communicating with the ATC and suddenly it stops sounding, like every message stops sounding but the messages still appear in the top of the screen, so it’s difficult to know when an ATC gives me an instruction, I can only know when the ATC headphones in the lower left part of the screen twinkle in orange and white, I know this is a problem with the app because in the Audio settings of the App ATC is at full volume and the cellphone is as well, what is causing this?
