There are many enterprise signatures at present. Many companies' apps are not so formal and can't be placed on the APP Store, so they will choose corporate signatures, or some companies' apps need internal testing, but submitting the review is a long and strict process, so they will choose to use corporate signatures during internal testing. If a certificate signs too many IPA packages or reports illegal applications, it will be cancelled.
Stable signature ensures the stability of certificate by controlling the type and quantity of IPA. Required contact button: 20 18624525
