Well done!? In the Arduino IDE, under tools there is a command to Upload Data to the ESp32.? Make sure you have your serial monitor closed first, then select.? The contents of the data subfolder in your arduino project wil lthen be uploaded to the ESP32.? Then you should be OK.
Most likely when there is a newer version distributed this will have to be repeated as the data in there could have also changed, eg the web pages.
