WAS very handy to monitor, maintain and control my wifi system. This last update caused me to go from a 5 to 2. After being logged in for a while I get the message that "cloud session has expired" the it just sits there with a black screen. I have to uninstall and reinstall it get it going again. You guys need to go back to the last version until you get this fixed. The iPad version is doing the same thing. PLEASE GET THIS FIXED ASAP.
