So I've had this sign for about 2 weeks now. I first used the "wifi" setting, which was fun. But then I decided I wanted to try the PC app - once I did that, the wifi setting seemed to not work. It kept telling me there were no devices even though my phone was connected to the "network signal" for the sign.Well last night I was trying to figure out why it wasn't finding my device - it turns out, it's a simple fix. You have to turn off your mobile data - that's it. Once I turned off my mobile data, the app FINALLY connected to the sign and I was able to control it from my phone. I personally prefer the PC app because it has more font options, but controlling it from the phone can be useful at some point.The app was another issue I had - when I tried to do my first sign display, the whole sign went haywire and was just a bunch of red dots. It turns out the settings in the PC app need to me modifified. In the Screen Settings option I had to change my screen size and that fixed the error.It really is a nice sign and works great IF you can figure out HOW to work it. They really should include better instructions, the only reason I figured these things out is because I'm overly patient lol
