Since WP won’t let me delete or edit this review, all I can do is comment.
1. I expect plugins to work easily. I don’t have the time or the expertise to figure out all the possible reasons why something might or might not work. As it happens, the one I ended up using worked as advertised in minutes. Whatever the merits of Popup Maker for everyone else, it didn’t work for me.
2. Regardless of the ticket response times you claim to give, I had seen some that had gone unanswered; hence the comment.
3. I don’t like giving low reviews. I know that software engineers work hard to create programmes that work; but if I’m sufficiently annoyed by something that doesn’t, then I’ll say so.
4. All this said, I will in future refrain from writing reviews until I’ve made some attempt to obtain assistance via the ticket system.
5. Have a nice day.
