Problem with recieving delayed data

MIT App Inventor Help
1

Hi! I've been having issues with the HTTP protocol for a project. I'm trying to send 5 blocks of data to an ESP32 via Wi-Fi, the problem emerges when I receive with the esp32 updated and outdated data. This is a picture of the Serial port of Arduino showing only one variable.

In red is the expected data, in blue the recieved one.

Any help is gratly appreciated

Code:

#include <WiFi.h>
WiFiServer server(80);

const char* ssid = "SSID";                  //REMPLAZAR POR SSID
const char* password = "PASSWORD";              //REMPLAZAR POR CONTRA
String msj;                                 //STRING QUE GUARDA EL MENSAJE RECIBIDO POR WIFI
                                            //FALTA VARIABLE DE MAGNETOMETRO!
float Giroscopio[2] = {0,0};                //VARIABLE DE POSICION DE GIROSCOPIO DEL DRON // X, Y
float DatosApp[5] = {0,0,0,0,0};                //VARIABLE DE DATOS DE DIRECCION Y POTENCIA DE LA APP
         
void WifiStart(){
  //Serial.print("Conectando a ");
  //Serial.println(ssid);
  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid,password);
  while(WiFi.status() != WL_CONNECTED){
    delay(500);
    Serial.print(".");
    }
  Serial.println("Direccion IP: ");
  Serial.print(WiFi.localIP());
  server.begin();
