Sorry for the misunderstanding then.
I would agree with that, if the platform was good enough to provide a quick and efficient service, and the marketplace is not!
I often receive emails very late from the marketplace (about reviews and questions), sometimes they have grouped messages (like: “You have 2 new questions and a review”), and the links are broken! I reported it to the marketplace support months ago and they never fixed it (It’s just a link to change…)
I had a positive experience with discord support channels, because the owner can reply faster and you can solve your issue sooner, it’s just a service that you may offer at your client, but it’s fair that you want to know if you paid for the product before offering you a “deeper” support.
