I have been trying for 6 months to get this feature to work. I have an android phone have downloaded the WhereYouGo app. I double checked the credentials and file location. a friend suggested I try to download from cgeo, but I get the exact same screen/error. When I click on any cartridge, a screen pops up with "Download Cartridge" on the top. A button on the bottom for "Download" I tap on Download and another pop up appears with first "Connecting" then "Logging In" then Downloading - then "Download Error". Same thing every time, and with cgeo. I have friends that download the same cartridge with no problems on their phones. Any suggestions????
