Urgent: hardware serial not working

[kevo16]

Hello I have a project for university that comes very close and my servo's start flipping when I use softwareSerial for my HC-06 module with my arduino nano every. I decided to use the hardwareserial ports 0, 1 but my arduino isn't responding to my bluetooth module and normally the usb connection wouldn't work when I connect the bluetooth module but the usb connection still works fine...
I cross wired my bluetooth module so RX(BT) --> TX arduino and TX(BT) --> RX arduino. I have an app to send the string 92 to arduino and it works fine when I use softwareserial. What can be the problem? Many thanks in advance!

EDIT: I also tried with changing Serial with Serial1

code:

void setup() {

  Serial.begin(9600);
  delay(500);
  pinMode(3, OUTPUT);
  digitalWrite(3, LOW);
  
}

void loop() {

  if(Serial.available()){
    String input = Serial.readString();
    if(input == "92"){
      digitalWrite(3, HIGH);
    }
  }
}

On the Nano Every, the USB connection is Serial, the RX & TX pins are Serial1.

Thank you for your quick answer. I changed to code to this:

void setup() {
  // put your setup code here, to run once:
  Serial1.begin(9600);
  delay(500);
  pinMode(3, OUTPUT);
  digitalWrite(3, LOW);
  
}

void loop() {
  // put your main code here, to run repeatedly:
  if(Serial1.available()){
    String input = Serial1.readString();
    if(input == "92"){
      digitalWrite(3, HIGH);
    }
  }
}

but still nothing. Am I doing something wrong?

Does your app send any type of line ending character, such as newline or carriage return, in addition to the "92"?

Yes, thank you very much. There was indeed a carriage return being send, everything works fine now! (Kinda feeling a bit stupid right now but was really stressing)
