Can't Enable Public link (Enterprise)

I've been having an issue with enabling a Public link for external users to access our apps. When I go to Share -> Public, I get the following error message:

The public apps feature is not part of your plan.

We're on self-hosted Enterprise, Retool versions 3.2.3, and have been able to do this in the past -- I only a few hours ago temporarily disabled the public link and encountered this error when trying to reenable.
