Hi,
I’ve just tested on the latest version of Sensei LMS and it’s working well. I suspect another plugin may be conflicting with this plugin’s behaviour. If possible, I would recommend deactivating the other plugins on your site and see if that fixes it. You could then reactivate the plugins one at a time until you find which one is breaking the functionality.
If that doesn’t work, the next step would be to test on a different theme.
If that still doesn’t work, please open the page in Chrome, click on the arrow, and then open the DevTools console by pressing Command+Option+J (Mac) or Control+Shift+J (Windows, Linux, Chrome OS). If there are errors, please take a screenshot and include it in your reply.
Thx!
