Error when losing coupon and try to regain it

Hi, congratulation for the great component!

I have an issue working with it and I need your help.

I created a coupon that is enabled when someone orders quantity over 10 items.

I am adding 10 items in my cart and inputting the coupon. So far so good.

If I remove one item the coupon disappears, that's great.

If I add again one item, I cannot input again the coupon, as I am getting the errror "An error has occurred while processing your request" and I cannot do anything to make it work, refreshing the page isn't helping so I need to abandon the cart.

Is this behavior normal or a bug that need to be fixed?

Thanks in advance.

Thanks for your reply!

I am using:

Joomla 3.9.19

Virtuemart 3.6.0

VP One Page Checkout 6.6.1

Glad to know it's a bug and not the way it was meant to work :)

Thanks a lot! I sent you a pm with the credentials.

Looking forward for your response!

Thanks for the access.  It was an issue with AwoCoupon, I have fixed it in your installation, and will be updated on the next release.

Thank you very much!

Can you please send me the files that I must replace with instructions? I gave you access to a clone, not to the live site so I should do the changes there as well.

Thanks a lot! That did the trick. Now it works as it should!
