@kees No, its to do with the fact that not all browsers are written the same. for best results always use google chrome as its the most upto date with web development standards.

Hi Dieter,

Do you have any new information about this topic. I‘m struggeling with the same problem, that i can‘t flash from ESPHome to my Atom Lite ESP32 IoT DevKit (Esp32 pico).

@felmue ah okay, perfect! Thanks!

@ajb2k3 thanks for the tip but unfortunately I can't access the USB port in my setup, so I'll have to go through the pins anyway.
