I bought the software from 'wh-satono' and have used many of their products. Overall, I'm satisfied as a customer; they have helped me with many issues and even provided key replacements for software that wasn’t working. As for the app called 'TikTok', it's a piece of junk. It has issues connecting to its own server. Imagine an app where you're asked to use a VPN just to connect to its own server. There's no solution for connection errors. The only advice given is to 'keep trying.' If you have money to throw away, then go ahead and buy it.
