TolpuddleSartre:
Without actually writing your code for you, I didn't know how to make it more obvious, so I thought maybe bold/underline might do the trick.

im pretty sure the problem is with newData = false , here is the whole code minus what starts it in the loop.

void recvWithEndMarker() {
    static byte ndx = 0;
    char endMarker = '\n';
    char rc;
    
    while (Serial.available() > 0 && newData == false) {
        rc = Serial.read();

        if (rc != endMarker) {
            receivedChars[ndx] = rc;
            ndx++;
            if (ndx >= numChars) {
                ndx = numChars - 1;
            }
        }
        else {
            receivedChars[ndx] = '\0'; // terminate the string
            ndx = 0;
            newData = true;
        }
    }
}

void showNewData() {
    if (newData == true) {
        Serial.print("This just in ... ");
        Serial.println(receivedChars);
       if (strcmp(receivedChars, "test 2") == 0) {
       Serial.println("working 2");
  }
        newData = false;
    } 
           if (strcmp(receivedChars, "test 1") == 0) {
       Serial.println("working 1");
      
  }
        newData = false;
    }

please go ahead a rewrite it because i dont know what your talking about
