Excellent contents but Too laggy, not very responsive UI – Lang Kingdom Review

I’m really live the lesson and teaching approach. I used to learned on hellochao web version for a while (used to learning the course English 365). It’s a good course. But The biggest issue that this app is too slow. For example, while take memorizing testing, clicking on micro button toggle it on and off because of delay to activate the mic. Other features also taking too much time to respond. I’m using Iphone X, so I don’t it my phone cannot load the app. The UI is not friendly. Too many menu and button.
