If we transfer ownership of a form by moving them to main account's shared folder, do the forms use main account limits, or the sub account user limit

So, if I'm a sub user, and I create a form in My Forms (outside of the shared folder) then move that form to the folder that's shared with me by my department's master account (upgraded license), then suddenly that form adheres to the limits of the master account instead of the response limits of my own free account?

If you transfer the ownership of the forms to a different account, the forms that are transferred are immediately using the limits of that main account - of the account where the forms have been moved to.

So following the example above, if they are moved from the free account to the main account and transfer is confirmed, these forms belong to the main account and will utilize the submissions and storage space of that main account.

The sub account user will only be able to see them and be allowed to continue with the actions allowed by the main account user.

This is also true if multiple sub-account users can see the same folder and one transfers the form - all could see it, but the main account would be the owner and its submissions would be used.
