ESP32 switch example fail to start conection to st

[Andorezu]

Good day

I tried to run the ESP32 switch example but when I pressed for 5 seconds the button the next message appeared.

W (45182) [IoT]: st_conn_start(1226) > Can't start it, iot_main_task is already working(2)

How can I solve this issue?

Below I add all the information the monitor shows.

@Andorezu Thank you for having interest in the sdk. We are currently looking into the issue.

Meanwhile could you let me know what you are trying to do? If you were following the instruction on ST app while onboarding, actually you don't have to press the button 5 seconds. By just powering on esp32, the device is already ready for onboarding state.
So when you see the instruction saying pressing the button 5 seconds on ST app, please ignore it now.

Anyway we will prepare the patch for the issue. Thank you for reporting.

@junyoun-kim thank you for your reply.

I made a mistake with my ST app on my devices, it was not updated, after updating the apps on my devices everything works great and you are right, no need to press the button.
