Instagram keeps sending verification codes to old email even after change

I recently changed my Instagram email from email to email2 via the Meta Account Center.
The change went through successfully.
Under personal info, it only shows email2 now.
However, when I try to change my password (or do certain account actions), Instagram says
"We've sent a verification code to email1"
The problem is: email is no longer linked to my account. However, Instagram still sends verification codes there. I obviously can't receive them.

Has anyone experienced this before? Is there any fix for it?
