I haven't encountered this before: I have 2x Record Types (both confirmed Active) on a custom object and both are each assigned to a unique page layout. I double-checked that each page layout-to-Record Type assignment was correcly laid out along with the corresponding Security Profiles (this object has same layout for all user profiles).
When I try to create a new Custom Object record however, there is no 'Select [Custom Object] Record Type' picklist page, the user is immediately defaulted to the 'pre-Insert' Edit Record page.
This is frustratingly basic, is there something else I am overlooking that would cause me to be unable to first Select the Custom Object Record type?
