Sorry,I changed it for public.

@ajb2k3
Thanks for your advice.
I'm using UIflow-Pico v1.11.8. and UIflow1.
Of course, I entered the address written on the label into the UIfow

Several Pico's recently purchased from the official store cannot connect to UIflow.
Previously purchased ones can connect they have different MAC address labels.
The one on the left side of the picture cannot connect,and on the right side that can connect. The one on the left seems to be able to connect to Wifi, but UIflow does not recognize it.
What should I do?
