There are currently 2 active certificates in the Apple enterprise developer account. One certificate belongs to one application is going to expire in a week, when I try to create a new certificate the option 'In-house and adhoc' is disabled with error text 'Maximum number of certificates generated'.
This is the first time I encountered this issue. There was a 3rd certificate also, I have revoked 3 days back as that certificate not required, still displaying the same error.
If anyone faced the similar issue in the past, please share how this can be solved.
