Disclaimer: I am using Inventor 2022 and do not know if this is still the case in the current versions of Inventor.
Currently, switching the active model state on an assembly back to Master can cause the user to be prompted to check subassemblies or components out from Vault (if they were suppressed in the previous model state). This is incredibly annoying.
It would be nice if either Inventor recognized this as the result of switching the active model state and did not prompt to check out children of the assembly as they become unsuppressed, or if this prompt was separate from the prompt you get when making actual changes to assemblies that aren't checked out, so that the prompt caused by changing model states can be ignored during a session/permanently without ignoring the checkout prompt on making actual changes to an assembly or part.
