<![CDATA[M5stack core doesn't work online: ""No permission. The device has been bound!""]]>Hello all,

I'm new to using M5stack core (the first and basic one). I installed the driver and followed the tutorials, everything was ok until I tried to connect and run a program from the M5Flow to the core in online mode. When I trying to connect or run a program the interface said the following message:

"No permission. The device has been bound!"

in the corner, where is the API KEY, it said the word "disconnected", if I press "refresh", it turned for a while in "connecting" and then go back to "disconnected"

The interesting part for me is that if I do it offline, everything works fine but when I want to work online I got this message.

I searched at the forum and in google and found no answer. Can anyone help me?

In advance thank you so much.

that what happened with me

Is any other idea?
