doesnt work

Worked correctly the first evening I installed it. Next day, I didnt change anything, but this app since then stays greyed out, is unable to connect to hue bridge because it doesnt even scan the network. I tried uninstall and re-install and tried to reset my hue bridge etc… without success.
Every other systems I have in my home who works with my Hue lamps are connecting to it perfectly each time. No problem at all. Its just this crappy app….
