Hi,
Yes, I can confirm that I am using LearnPress 2.1.6.1. Also, I do not have any page builders installed.
All of the lessons, including the lesson I could not delete, are empty. So I haven’t used ANYTHING to add content to them. All I have done is create the curriculum outline. When I realised I’d added the same lesson twice by accident I tried to delete it. That is when I hit the problem with deletion.
