It's just necessary to somehow run this app work in China ... to avoid cloning ... I'm not sure that this is possible, but suddenly there is such a prospect?
There is a technology banned in China (CallKit), so for now there is no such possibility. But probably the developers will decide this issue in the future
Right. And to solve this issue, you will have to rewrite the application, which is very difficult because the entire product already works fully and has a huge number of users who use it on a daily basis.
