Friend is online but its says she hasn't been for 4 days

Hello @HayleyDavis1! I hope that you are doing well!

With issues like these, please ask your friend to double check her account settings. Here's how:

Settings > Account > Privacy & Online Safety > Xbox Live Privacy > View details & customise > Online status & history > Others can see if you are online, click the drop box if it says blocked.

I hope this helps you out!

It may also be that your friend has the setting "Appear Offline" turned on. Ask her to check.

Yeah mines messed up today too.. On my card on here it says 170722, on my xbox its 171217, I got a friend to check, and if he just looks at it it says 170722, but if he compares games it actually gives me more points than i have 171237?? I haven't unlocked
anything for 2 days, and been online for both days, yet it hasn't corrected itself on here or to friends over xbox

Yes she is appearing offline even though she isn't, she tells me she is online but when I look it doesn't show. a few days ago I could see she was on but now can't and she hasn't changed any settings.

Unfortunately there is no way to recover it unless she played online at some stage. Then the cloud would have her last save. If she hasn't been playing at all online then there is no way to recover the lost saved data.
