In reference to both your topics about these libraries… This is part of your issue…

The ESP8266 in your case is ONLY acting as a Serial to WiFi transceiver (AKA as Shield), thus it uses different libraries and has different functions then a full standalone ESP8266.

I also use a Mega with ESP as shield… and am able to run without Blynk connection via this code…

This is for an auto reconnection routine…

#include <WiFi.h>
#include <ESP8266_Lib.h>  // ESP-01 Link
#include <BlynkSimpleShieldEsp8266.h>  // ESP-01 Link

void setup() {
  // stuff...
  wifi.setDHCP(1, 1, 1); //Enable dhcp in station mode and save in flash of esp8266
  Blynk.config(wifi, auth, server, port);
  if (Blynk.connectWiFi(ssid, pass)) {
    Blynk.connect();
  }
  // stuff...
}

void loop() {
  timer.run();
  if (Blynk.connected()) {  // If connected run as normal
    Blynk.run();
  } else if (ReCnctFlag == 0) {  // If NOT connected and not already tring to reconnect, set timer to try to reconnect in 30 seconds
    ReCnctFlag = 1;  // Set reconnection Flag
    Serial.println("Starting reconnection timer in 30 seconds...");
    timer.setTimeout(30000L, []() {  // Lambda Reconnection Timer Function
      ReCnctFlag = 0;  // Reset reconnection Flag
      ReCnctCount++;  // Increment reconnection Counter
      Serial.print("Attempting reconnection #");
      Serial.println(ReCnctCount);
      wifi.setDHCP(1, 1, 1); //Enable dhcp in station mode and save in flash of esp8266
      Blynk.config(wifi, auth, server, port);
      Blynk.connect();  // Try to reconnect to the server
      if (Blynk.connectWiFi(ssid, pass)) {
        Blynk.connect();
      }
    });  // END Timer Function
  }
}

This is NOT drop in code… you will need to examine it and extrapolate what you need for your own projects…
