Hi there, @sazelkhokhar… if the company email is associated with a Bubble account, you should be able to transfer ownership to that email/account by inviting the user on the Settings >> Collaboration tab and clicking the Transfer button (which will become enabled after you enter the email address). When you say it doesn’t allow you to do that, what do you mean? What are you actually seeing?
Oh, and this thread might be helpful, too.
Best…
Mike
