I would not say a Word if the plugin was free and I had not bought it. You present playlist functionality in the features.
Well, “nobody else is having the same problem” really? So when something is not working but nobody has found it yet – everything is working perfectly right? Tell me that when you add let’s say 40 videos to playlist you can not see this problem, and I will immediately shut. But I mean whatever, you do not have the will to help anyway probably. And my key? You can check my email address in the invoices list or what do you need it for? Believe me or not, I have bought your plugin – name: Pavol Nazarej, email@example.com. My project is confidential and I can not give you a link but I can create a special WP installation where I will demonstrate this bug to you. Sufficient enough?
Hope you will look into it.
