FortiManager is well suited for larger organizations which require unified configurations and IT departments that need quick turn around on firewall related tickets. I believe MSPs can also benefit with the use of the VDOM feature, if strict separation between clients is needed. FortiManager wouldn't be ideal for 1-3 site operations, unless their configurations are extremely complex or have a high number of active users.
Various bugs: The software is buggy, and if you don't have a good understanding of it's underlaying operation, you can get confused or stuck when pushing a configuration. There are lots of little quirks you will have to learn, which are not described in any documentation.
Conflict resolution: Occasionally, during larger changes, bringing new devices in, pushing a config will fail due to dependencies, conflicts, or other software bugs. This is somewhat time consuming because the error messages provided aren't descriptive
CLI Options: Some configuration changes require creating scripts that execute on each device, and can't be done via the GUI
