Post upgrade to Appian 22.1 process model is not showing write to data store and news feed smart services. Also getting invalid process message.

Quick steps to troubleshoot.

• Is this problem specific to your user account? Try doing it with any other user.
• If it still persists, then you can probably request a restart.
