[Problem with Spartan Assault - can't sign in - can't save progress]

I had issues with Spartan Strike signing in.  so I tried the Spartan Assault.  Same problem the game cannot connect to server to save your place!  I am using HP Spectre X360 convertible laptop.  I would appreciate any  help.  I tried Mircrosoft help chat with no result.

[halo spartan strike can't sign in]

I installed spartan strike on my new windows 10 laptop (hp Spectre 360) worked fine for a few day.  last night when I start the game, I get the error "WARNING  Can't sign in . Try signing in at Xbox.com, then start the app"  I am signed in and still can not sign in .  Please help.  I spent 4 hours with Xbox support chat with no result.  I have uninstalled and installed the app at least 10 times. I have returned the app and purchased again - still no luck.

Thanks
