Sketch is restarting again and again in loop if wdt_enable (WDTO_8S) is declared before Blynk.begin(auth, wifi, “ssid”, “password”, “server ip address”). If wdt is declared after Blynk.begin and router restarts the sketch hangs and app shows device offline. This problem was not there in Blynk library 4.0 and below. In that wdt works even if declared before Blynk.begin.

Anyone can help to tweak latest library for wdt to declare before Blynk.begin.
