Changed member owner on account and have lost content

Hello! I love ChatGTP, thank you.

I’m a plus subscriber and I went to update my email log in. I added a new member to my account with a new email. I made them the owner of the account and removed the old member/email. My issue is now for both emails if I log in my content is missing, even my bookmarked content doesn’t display, and it says I’m not a subscriber.

Thank you for any help.
