My form is still showing overquota message

My form has exceeded the 100MB quota. Then I deleted the messages and the space was released. However, the error message still remains: Form over quota! This form has exceeded its allocated quota.

How long does it take to normalize?

I cleared the form caches for your account (abccponei), can you please check if your form is working as expected now?
