Discount vouchers not valid for u-he products?

I know it’s now October but I have my voucher from June 2023. I had the same issue last summer when I upgraded and the year before that etc….. and the Christmases in between. When I look at the list of products that are available to me I know that the products available are already available in my version of the software. What would be a good idea in stead having to search through hunters of products to then find out you can buy this or that product with your voucher is actually let you k kw what products are covered under the voucher. I have an account with IK MultiMedia. I am not skating one product against another. However when you get a voucher with this company you click on the my upgrades/offers and your are given a list of the products that are covered by the voucher. I just put one product into my basket no discount, it was an NI product etc…. The message I got was this item was already discounted. I tried another product a bundle this time and exactly the same issue. It’s like looking for a needle in a haystack. Is there anyway that NI can actually display the products allowed by the voucher in your account. I have worked on databases myself and basically your client purchases the NI Collectors Bundle. When you purchase this bundle in the scenes behind you set up a template that has this or that product ticked that way when the client logs into their product from the net they can see what they have. I worked on financial services but the principle is the same. In the background your create a template that fits a certain product and what you can do with that ie login, view product details and values. You do this by ticking radio buttons in the background. You only need to create it once for the said product and this applies to every person on the database that has that policy. Same way with internal users you set up what they can and can’t do by using the radio buttons. Technically this is the same as a NI Product you tick off the products you already hold and subtract from the database excluding partner products not included in the deal. When I look at my offers etc…. I can see that I can upgrade or my offers and it offers me a product that I can’t technically regress back to ie standard because in the edition I have everything is included. I. Do have the option to upgrade to the collectors edition but that is in a special offer and you can’t use the voucher. In my account I can see offers beside my name and you click on this and these are partner offers which the voucher doesn’t cover. Now we have a sale on you can’t use the voucher on the Massive soundbanks because instead of being £44 they are now £22. You can’t win. The last time I looked at this problem I copied over what is included in collectors edition to a couldnt in excel. The ne created another column with the product and I sifted through the products that were not in my edition but in the collectors. Now that is something that me as an end user shouldn’t be having to do. My piece on the matter.
