After the Microsoft update of 1803 in May, the Microsoft Solitaire Collection became more impossible than ever. It seems we are getting the Error Code 121003. I've followed the minimal instruction to reset, reinstall, restart, sign in and out of XBox to no avail. I'm signed into XBox and can play other Microsoft games. The Microsoft Solitaire Collection is my favorite set of games but it isn't worth the frustration to play it. I've played long enough since the update to know that the app has changed again. The choice of solvable and random games is gone. I have managed to play daily challenges but not the events.
There are problems with the update and, of course, no tech support from Microsoft or XBox.
I'm using a HP PC. I'm not on wifi. I wasn't having issue until after May 3 when my PC updated to 1803.
I'm sure that's just a "coincidence"...NOT.
If anyone comes up with a solution, I would love to hear it. Good Luck to all.
