Payment Successful Automatically

Hello!
Been using the plugin for 2 of our websites, the plugin works well but after the payment is complete, the status of the order is not updated/ changed to processing automatically.

We have to manually update the order from “pending payment” to “processing”.

How do we get this done automatically?

Earlier when we started using the plugin it worked perfectly.

Kindly provide a fix for the same.

Thanks & Regards ??
