Building more than 12 OAuth apps in tenant - oauth_exceed_limit

Hello! We are in the same kind of trouble. Could you kindly help?
We are creating Account level Oauth apps.
In the Zoom App Marketplace, we chose “Build App” from the “Develop” button on the top, and then the error messsage “oauth_exceed_registration_limit” appeared.
How can we solve this?

We have only 5 OAuth apps as the “Created Apps” in the “Manage” screen.

We also found the below thread.

This thread says that there is a limit on number of apps created within a 24 hour period.
However, when we tried creating app on another day, it resulted in the same error.
The thread is old(2020), so maybe the specifications have changed.
