It simply doesn't work as advertised
It simply doesn't work as advertised. Save your money! I bought it to specifically transfer Whatsapp stickers (they have an article on their website saying it does exactly that), and it didn't work. To make matters worse when I asked support about it they replied "As for the stickers issue, sorry to say that our program does not support the function you want now. However, we will collect your feedback as a demand request and report to our programmer to carry that feature in our feature updates." It's just plain false advertising.
