It looks like you have a debug level set in your IDE options, and the other output in the serial monitor (the data from Blynk) isn’t what I’d expect to see when your app displays the information that you posted in your fist post.
Can you turn-off the debugging in the IDE then repeat the process and explain in detail (with screenshots if necessary) what you are seeing in your app during the provisioning process and what you are seeing in the serial monitor at the same time.
