I'm just starting out with Adobe XD and I'm going through a course at Lynda.com to learn it. The lesson that starts describing the interface shows an "add-ons" button just under the home menu. I do not see that on my version of XD. I'm using the starter version 33.1.12 on MacOS Catalina. Should this be available in this version? I see that there's a plugins menu but I don't see the add-ons.
Thank you for reaching out. You probably are looking at the old interface. XD has evolved a lot in the past 1 year.
I would recommend exploring (https://letsxd.com/) and XD User-Guide for updated content on XD. We'd love to listen to your feedback about these resources.
