iOS 13.3.1 limits free developer accounts to 3 apps and app extensions. As a workaround, we now allow up to 3 “active” apps (apps with installed provisioning profiles), as well as additional “inactivate” apps which don’t have any profiles installed, causing them to not count towards the total. Inactive apps cannot be opened until they are activated.
