So from starting this is happening whenever the tool is on sale on Appsumo, the tool works and in normal days its not, it's not only me many users faced that, and Krishna doing this knowingly, people like him only think about their pockets, not your hard work, and your hard earned money, to test this while I was on Tier 3 of Lifetime, I conducted a Search for Keywords which returned 0 as usual and after that I placed a support request which got no answer and after that I applied for Refund and I got only 50% Back, Krishna Anubhav just halved my money, after the refund my plan also downgraded to Free, and I again did the same keyword search and that returned 1001 Keywords, you know right? it was designed to not work on paid plans or designed in a way to work for or work randomly, and if you are just a guest or trying the tool it will work so you can buy the tool.
