What does sign in or renew the subscription mean when I try to play a game on Xbox One?

No, it’s a game I purchased the physical game through Gamely.

If it's an online only game then you need to renew to play

If you are trying to access multiplayer on a non online game you still need a subscription

Hi, I hope you're doing great out there. I am an Independent advisor and I am here to help you in regard to your concern.

This may mean that you were able to play the game via Xbox game pass or someone is game sharing with you which is why it is asking you to sign in using the account where the game was purchased.

We need to validate, kindly sign in to https://account.microsoft.com/billing/orders and check if you can see the game order for the games that you're trying to play from there stated as "completed".

Once you were able to see the games, please remove and re-add your account to re-sync the license.

Hi There

This is what I could find for this specific error code:

Error 0x803F900A occurs when you try to play a game on Xbox One

You get the following error code when you try to play a game on Xbox One:

0x803F900A

This may mean that you need to sign in or renew your game subscription.

Solution

To play your subscription game, use one or both of the following steps, as needed:

• Sign in as the subscription holder for the game you’re trying to play.
• If you’re already signed in as the subscription holder and the game won’t start, you probably need to renew the subscription in Microsoft Store. You might also find it listed in Settings > Subscriptions.

For help with signing in, see the Xbox One Connection and Network Solution.

For help with subscriptions, see Manage your non-Xbox subscription payment options on
Xbox One.

If that does not work try signing out and signing in again.

What I mean is that whenever I try to sign into another account to play multiplayer games I can't sign in also my Xbox live gold has been renewed but I am having problems with purchasing games for free I even changed the password for one of my accounts but
it still does not sign in.
