For the past two days I have been unable to test anything with the AppyBuilder Gold companion. I even uninstalled it and installed it again from the Play Store and downloaded version 3.18 from the link you posted elsewhere in this forum.
When I enter the 6-digit code the bar code on my laptop disappears, so it has connected with your server. But on the phone it just sits on the login screen, with nothing happening?
UPDATE: It started working again, although very slow.
