Submission blocked due to 3-account limit despite Pro upgrade

I was facing an issue while submitting my track where the platform showed an error stating that a track can only be submitted by a maximum of three different accounts.

At that time, my submission was blocked.
I have now upgraded my current account to Pro, and after the upgrade, I’m able to submit the track successfully without any issues.

Sharing this here in case it helps the team review or clarify how the account limit behaves before and after a Pro upgrade.
