I'm also having major problems with this app. I've used it in my house for about 1 and a half years. Even on different devices all successfully. 2 weeks ago it became unusable. It won't connect to my Mac or my PC. can't connect or even setup new connections. I have reset my one router many times. I've uninstalled and reinstalled it on all my Android phones dozens of times. It sees my server but won't connect or won't authenticate. So what's the solution anybody? Can I get my money back?
