Hi cdowis75,
Thanks for contacting us. I completely understand. Unfortunately, it seems that it does count it as a separate lesson :-( I will let our development team know of your thoughts on this. That way they can make any necessary changes regarding this issue.
Again I'm really sorry about this and I'll see what I can do :)
I am a Premium member and supposed to get five lessons with Mentor. When I reach my limit I want to go back and review the previous lessons, but it sometimes tells me I have to upgrade.
I really feel that the five limitation should be for NEW lessons and it should allow me to review my previous lessons without any charge. Sometimes it allows me to do the review but most of the time it brings up the upgrade window.
Please fix. Thanks!
