Syncing data problem.

Games Halo 5: Guardians
1

Since 2 days ago, every time I open HALO 5, it told me “Syncing data for HALO 5:GUARDIANS”
And few second later it just told me “We couldn’t get your latest save data. Try again or use this game or app offline.”
No matter how many times I’ve try, it just keep showing me the same message.

So WTF HAPPENED!!!
It’s really PISS ME OFF!!

I’ve restart my XBOX so many time.
Delete my local saved data.
Reset everything plenty of times.
Try everything, but it still told me “We couldn’t get your latest save data. Try again or use this game or app offline.”

SO IF I CAN NOT USE ANY F-WORD HERE, THEN THERE IS NO WORDS I WANT TO SAY!!
