We recently paid for a lifetime license, after a few years of limited license extensions. We had no problems in the earlier years when our license was time limited, but that all changed when we finally paid for the lifetime extension. This turned out to be the biggest mistake we've ever made for our forum. $90 of our money, donated graciously by our staff and loyal members, straight down the drain!
We've been ghosted on our support ticket submitted for a broken addon. There are multiple bugs that allow users to bypass the functionality, and additionally we found that the addon was the cause of an issue we were experiencing with the REST API not working on some of our other custom scripts. The dev has not even acknowledged our attempts to get help despite repeated requests through their support website, yet when we finally gave up and disputed the sale through PayPal, they were VERY quick to respond and deny us there, claiming they were in fact providing the product as described. Imagine that! Guess they just don't care about anyone's issues they've reported here, so long as they got their money from you!
We will never use this add-on again. It is now permanently uninstalled from our site, no thanks to the developer, because not even the uninstaller script worked without manual intervention! As it is, it is completely unusable and there is no sign that will change any time soon.
To anyone who stumbles upon this add-on, all I can say is stay away. Stay far, far away.
