Can't Sign in with my account, just like so many other people I see on here. Error Code: ...

There is a known issue at the moment.

Keep an eye on
https://support.xbox.com/en-US/xbox-live-status and they will let you know when the issue is resolved

ugh hopefully the error code itself isn't the problem and just comes up cause it doesn't know Wtf is going on. Thers so many people with this problem right now I can't see them willing to lose so many customers. but maybe I'm naive.

It happens with every other backwards-compatible game I try.

My password is not longer than 16 characters.

And last, but not least: I can't even access the Guide in the emulator, because it doesn't start. It just shows a short screenshot of the RDR-sign and then closes with the error-code...

Many, many, many other people seem to have this problem in this forum and noone knows how to fix it - it should be there since the october-update, but Microsoft doesn't care... yeah, nice.

It would help if you could provide us with the exact error code you get. If you told us the code like 0x0815 1234 or whatever, we could try to search for the cause of those error codes.

But just with just the info about getting "so many errors", we can't really help here

After seeing how many issues with auto renewal people complain about on here, I can't help wondering if the easiest solution wouldn't be if the company just set it to not auto renew by default, and offered the option to turn it on at sign up, rather than
the other way 'round.
