Just got a MatterControl Touch to use with my Rostock MAX 3D printer kit. Tablet has working WiFi set up.
Main interface shows a red "1" on the Updates link. When I click on it displays on screen "Launcher: Update Ready to Install".
Every time I click on it it switches to "No Update Available". Then when I go back to previous screen, goes back to showing that 1 update is available.
Have turned tablet off and back on several times, which did not help. Switched tablet from Dalvik to ART and re-tried, then back again, still no success.
Was successful in downloading and installing an available update to the MatterControl software.
OS: Android 4.4.4
