Is the Instagram app cloning method not working anymore?

I saw people are getting errors while cloning, does it still work on rooted android?

If you are talking about Jarvee, the cloning is working on my side. I’ve just used that option.

You have built in cloning on Xiaomi, Huawei devices without root.

Are all models of those brands have built in cloning?

Built in dual app.

Thank you I think I’ll get one. Is there any tutorials about this?

Nope. Just settings-dual apps and choose IG

Does Dual app only clone one or as many as you want?
