Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.

Hope you're doing great today despite this William

Please answer the following questions to assist you properly :

Is this happening on Xbox, right?
If yes, what console do you have?
Is this happening only with this game? Or if you try with a different game the issue persists?
What message are you receiving specifically inside the game? (If possible attach a picture)
Do you have a Live Gold / Game Pass ultimate subscription active? (Most of the paid games has this requirement)
And, what did you tried so far to fix this problem?
In that way I can advise you different things or how to proceed

Also some games just kinda force you to get the special editions i dont know if its on purpose but rainbow six seige for example you cant get it

Do you think I would of lost saves data on Rainbow Six Seige such as unlocked characters?

Ive been playing a huge amount of Rainbow Six Siege. Easy game to just play a match or two, go do what you gotta do and come back later.

Ddoss happens a lot in rainbow six seige
