Upsellio ‑ Discounted Upsells

It just stops showing upsells and addons for no reason. Every time you need to contact the support to fix it. Every time you contact the support you need to prove that there's a problem. Then they say it's fixed then you check and it's not fixed then the guy in the support just ends the chat to pass you to another person and then you need to go through the whole process again. Not recommended.
