Solo TeamBuilder Online Dynasty becomes inaccessible

This needs acknowledgement from the College Football 27 team.

There appears to be a persistent issue specifically affecting Online Dynasties using TeamBuilder teams, and reports of it have now been appearing for roughly a month.

This is not a normal internet connectivity issue.

The pattern is extremely consistent:

TeamBuilder Online Dynasty works normally for an extended period of time.

Eventually the Dynasty becomes corrupted/inaccessible.

The Dynasty will still appear in the Dynasty menu and will begin loading normally.

Once inside the Dynasty hub, the user has only a few seconds before being disconnected.

The game then displays the message that the EA servers are unavailable and returns the player to the main menu.

Other online game modes continue working normally.

Other Online Dynasties can continue working normally.

 Restarting the console, restarting the game, reinstalling, resetting network equipment, clearing cache, and standard connectivity troubleshooting do not repair the Dynasty.

 Once the problem occurs, the affected Dynasty appears to be permanently inaccessible.

Most importantly: multiple users are reporting this happening specifically with TeamBuilder Online Dynasties.

There are now numerous reports on these forums describing nearly identical behavior. Some users have experienced it on more than one TeamBuilder Dynasty.

This strongly suggests that this is not an individual connection issue. Something appears to be happening to the Dynasty save/server state that causes an otherwise functional TeamBuilder Dynasty to become inaccessible.

I have also personally confirmed that my other online functionality works. The problem is isolated to the affected TeamBuilder Dynasty.

I have also spent upwards of 12 hours building custom TeamBuilder schools specifically so I and other users can use them in Dynasty mode. That includes creating logos, uniforms, fields, branding, and complete custom programs. At this point, I have invested a significant amount of time into a feature that we are effectively unable to use for its intended purpose because the Online Dynasties I create with these schools eventually become unplayable.

Platform: Xbox Series X
Game: EA SPORTS College Football 27
Mode: Online Dynasty
Team type: TeamBuilder
Issue: Dynasty loads briefly, then disconnects and reports EA servers unavailable
Duration: Approximately one month / persistent
Frequency: 100% once the Dynasty becomes affected
Workaround: None found
Result: Existing Dynasty and all progress become effectively unusable

At this point I am not asking for another list of network troubleshooting steps. Those steps do not explain why other online modes and Dynasty saves work while the affected TeamBuilder Dynasty does not.

What I am asking EA for is:

Confirmation that the College Football team is aware of the TeamBuilder-specific Dynasty issue.

Confirmation that the development/server team is investigating it.

Information about whether affected Dynasty saves can be repaired rather than requiring players to restart.

An update on whether this is being targeted for an upcoming title update or server-side fix.

If you are experiencing the same issue, please upvote this report and reply with your platform, TeamBuilder/standard team, number of users in the Dynasty, season/week when it happened, and whether other online modes still work.

There are enough reports now to establish a pattern. Players are losing Dynasties they have invested dozens or hundreds of hours into, and creating another TeamBuilder Dynasty is not a real workaround if the same issue can eventually happen again.

We need acknowledgement of the issue and an update on its status.
