We are having a lot of bugs since installing this plugin.
First, it wasn't supporting coupons and we had to develop this part ourselves and the solution that the developer proposed isn't practical.
Then, we found many issues regarding pending payment and subscription. The plugin doesn't add the customers as subscribers for recurring payments in easy digital downloads and the order status sometimes keeps in the same status "pending" although the user had completed the purchase. And sometimes, the status became completed then pending suddenly.
Just weird things happen with the plugin. The plugin is a payment gateway and any payment gateway should be released after a lot of tests.
The code quality is horrible and the author is repeating the same code a lot of times which makes it difficult to debug.
Finally, please note that the author isn't going to accept any refund request.

Thank You!!!
