I have been using spacedesk for a couple of years now and I am happy that I found this software. I am glad that there are people making this possible but I have experienced just today after I updated the app that when I connect to my phone it shows "Connected - Display Off" then it disappears and has a black screen. I waited for a couple of minutes but it still didn't show anything. I tried to switch the display mode to "Show on 2nd screen only" and it showed "COnnected - Display off" again. I hope there is a fix from this... I tried to restart my phone. Restart my laptop. Uninstall the app from my phone and it still didn't work. I tried to turn off my wifi and turn it back on and it still would not work.
