 * I am using the PAYSTACK PMPRO ADDON. After a payment completion on paystack, 
   and the user is redirected back, instead of seeing the confirmation page, the
   user sees “invalid reference”.
 * Do you have an idea on how this could be resolved?

 * For pro or commercial product support please contact the developer directly on
   their site.
    This includes any pre-sales topics as well. As the developer is 
   aware, commercial products are [not supported in these forums](https://wordpress.org/support/guidelines/#do-not-post-about-commercial-products).
   I am sure they will have no problem supporting you there.
