ESP32S3, WiFi provisioning.

[beryllium]

Hello, I am trying - in vain - to get the Wi-Fi provisioning example working with an ESP32S3 processor. If I use an ESP32 processor (DEVKIT with CH340), I have no issues, but with the ESP32S3, the SSID of the Access Point (softAP) cannot be discovered by the "ESP SoftAP Prov" smartphone app, and is not visible with any Wi-Fi network monitoring tools. Question: Is there a specific configuration required for the ESP32S3? I'm using an ESP32-S3-DEVKITC-1. Thank for your help.
