I had an error in one of my Gerber projects which I've noticed one hour after I've submitted the files. The website doesn't allow you to change the submitted Gerber files. I've emailed both nicole@easyeda.cc and "Let's chat" about this and I've got no reply after 3 days. This means probably I'll receive the board with the error I've made and I will need to cut a trace and solder a wire. That's fine but for my next projects I'll use another PCB house from https://pcbshopper.com/ I was expecting to be able to correct an error after just 1 hour but apparently not so with EasyEDA.
