Invalid Account - Xbox One

@ItsLoucifer 

Sorry to hear about the trouble you've been having trying to load into Apex Legends. You don't have to call in to try this step below, let's see if this works first.

Visit Help.EA.com and make sure you're signed out. Click login at the top so it prompts you to sign in. Click the Xbox/Microsoft button to login so you use your Microsoft account information to log into our site.

Once you login that way, it should prompt you to create an EA account which will link your Gamertag to that one. If it doesn't prompt you to create an account, that means you've already synced your Xbox Gamertag to one a while back somehow. Click on Accounts>Change Email address at the top to verify the email address that's already linked up. (You can change it there if you need to as well)

Once you've signed into our site and completed the account creation process, restart your Xbox and try loading into Apex Legends again.

Just to avoid any confusion though, when you load up Apex Legends it's not going to ask you to sign in every time. You'll be prompted to sign into the servers to connect to them, that's all. If it's getting stuck at that point, try these steps below to help repair any connectivity issues you might be facing.
