Hi @staticvars,
Thank you for your reply.
After canceling the export job, do you see any errors in the History section of the extension?
As a quick test, I recommend creating a new test database with a few users with the app_metadata.authorization.groups attribute. Then retry exporting those users (e.x 3 users), which should take moments to export.
I look forward to your update.
Thanks,
Rueben
