Not working when not connected to Serial #27

The WiFi Manager doesn't work when powering the ESP32 over its VIN Port, but does when powering it through USB. I'm simply using the Code from the Async_AutoConnect_ESP32_minimal.ino example. I already remove the while (!Serial); delay(200); line. Is there a simple fix for this?

Turns out there is a more general problem with powering the ESP32 on the VIN Pins, which has nothing to do with the library.
