affter i reset my pc i got this error trying to start the game "Phantasy Star Online 2 can’t open because it is offline. The storage device might be missing or disconnected."
also the icons grayed out im sure there must be a simple fix for this but i have no idea what that would be. 
I am having the same problem this morning. "Phantasy Star Online 2 can’t open because it is offline. The storage device might be missing or disconnected." I have tried going to the app settings and using the repair functions and not dice
@morizan Ok. Im not sure if repetition did it, but right click on the tile, go to more, then app settings. Select repair and wait. It will eventually show you a check mark. Dont try to launch it yet, restart your system. When i followed those steps i was able to get in
It's a well known problem. it means the game deleted itself. Right now we don't have a solution so we wait for sega or Microsoft to do something.
This happened to me while swapping accounts, the secondary account on and used through xbox.
I re-installed seems to be working fine now.
Thank you Niarudi.
