@dwadia the standard shield sketch shows a rate of 115200 but if you study the sketch including the notes then you will work out that this is just for Hardware Serial (Mega, Leonardo etc).
Following the url link in the sketch takes you to this excellent page for AT set up https://github.com/blynkkk/blynk-library/wiki/ESP8266-with-AT-firmware
It is quite clear that the baud for Software Serial (Nano and Uno’s etc) must be 9600. Well worth looking through Blynk’s AT set up guide and the page they link to by fellow Blynker @Rom3oDelta7 at Solved disconnect/cmd skipped etc issues. My advice
ESP’s come preconfigured to various baud rates and it’s quite common for them to be 115200 but you can’t use this as a shield for Nano’s and Uno’s. Blynk’s AT page gives details of how you make the change.
