Good evening to everyone
I'm using the wifi manager on esp32.
Everything works fine as soon as I program my module, but once I make the first connection to a wifi network, if I try to connect the module to another network, the module starts with autoconnect but if I click on the configure wifi button I do not see any network. I attach an image

I'm using the esp32 wroom module on a DEVKITV1.
Initially the wifi manager works, but after connected to a network when I try to change from my phone even pressing the scan button I see no network anymore.
Forgive me, but I am not an arduino expert

I can attest that using https://github.com/espressif/arduino-esp32 core and https://github.com/tzapu/WiFiManager/tree/development works fine for me on WROOM32.

Yeah they are clearly using some non official esp32 fork from the pics

I don't know if this will be helpful but I got same error event: mismatch or invalid event, id=63 using Basic.in example. The problem went away when I removed , "password" from res = wm.autoConnect("AutoConnectAP","password"); // password protected ap.
