Hi, there.  Has anyone tried to use the Congrea virtual class plugin with Moodle 3.3?

The latest version supports up to Moodle 3.2. We managed to install Congrea on our 3.3 test instance, but when a Congrea activity is created and accessed, the tool keeps trying to access the server repeatedly.

Can't seem to find a way to contact the developers either.

Seems like a very good plugin, if we can manage to set it up properly...

Thanks for any help.
