100 games missing

As one user mentioned be careful doing this because you can get banned especially since you are bringing attention to it and wondering why this has happened? smh

hi

just want to point out that you haven't done anything wrong your account as stated also has a game pass attached to it so don't worrie about the theft that some people are telling you its not the case if you also have your own game pass this is only the
case if your using someone else's game pass to play there games.

what this does seems to be though like others has said is that she has changed her home Xbox from the one you have to ever a new one or a different one this will remove anything of hers from that Xbox but she wouldn't have lost anything as it would all still
be attached to her account.

if this seems to not be the case please ask her to get in touch or get in touch yourself again and I'm shore we can help you out some more

(just adding to this as I noticed u said lent witch means its unlike she has another Xbox to move her home to a new one, this could be simple because when u put your account on there u may have selected it to be your home console witch would have removed
her but as long as she has her password when the Xbox goes back to her she can just set it back as her home console and this should resolve this issue)

hopefully this was helpful

She most likely set her home console to another which doesnt give access to her games for you anymore

to access her games you would need to have her account set as home xbox.

Her games might be located in her Full Library where the My games & apps section is.
