These games are fun... when the app works. About 60 percent of the time when I try to open the app, I get a load connection error. FAQ refers to versions on Win 8.1 & Xbox - dumb. I can play offline, but I lose my progress. Annoying. My Android OS & the app are kept up to date. No other apps I have installed have this problem. It's nonsense like this that supports the common perception that Microsoft continues to put out buggy junk software. And if it works this badly, why would I pay to upgrade?
