In this April, on CPS enabled orgs pagination got introduced on company apps. According to the doc site's change log, maximum 100 company apps is returned in an API call. On other endpoints that already had this feature (ex.: API products, Developers) it is 1000.
Why is this inconsistency? What about Company and Developer Apps? After a 30s hacking it seems pagination is also available on them - although it is not mentioned in the official document yet - but I haven't checked the maximum limit yet.
