Hi Karl!
Thanks for taking your time to report this.
Unfortunately, the PDF tickets will only work if the user is logged in so that only the user who purchased the ticket can access it.
We have a report to improve the functionality of this extension so that it can be possible to get the PDF tickets without being logged in including a security variable in the url for the tickets.
I will link this thread to the report so we’ll let you know once we ship a new version of this to include this functionality.
Best,
Victor
