For Deep-Silver.
I have installed your wonderful contribution in my store and eventhough I think -along with everyone else- this is one of the best contributions ever I've also noticed that some of us have had the same problem with PayPal -IPN and/or Standard- in regards that when a customer uses points either to pay part or the full order, points don't get deducted of the total to be pay. As well as the fact that if customer changes his mind and go a back, their current points get lost.
When I first faced this problems, I went through the entire forum looking for a solution as I was sure someone with the same problem may have already came up with a solution but, after reading lots and lots of posts and tried every single "solution" even that most of them refer to PayPal IPN (I use PayPal Standard)and found that none of them really work I wrote the post below hoping someone could've help me.
I'm aware you don't use and even like PayPal as you said way back a while ago in some post when you started to be asked about this but if you check the forum, since you released Points/RewardsV2.1rc2a many of us still have this problems and unfortunately we can't simply give up PayPal due in our countries our customers want to pay us through them.
I know you haven't been around the forum for quite a while, but if you get to read this, I really hope you can help us all out with a solution not because we want you to solve our problems (as you said once) but because no one knows this contribution the way you do and this a very recurrent issue at the forum.
Wishing you the very best, receive my regards.
