My mobile phone is the IOS system, and the network is smooth, but the APP of this platform is super difficult to log in. Every time I close the APP and then open it, I have to log in again, and then sometimes I can log in and sometimes I can't. Today, the network is normal, but I can't log in. I'm so angry, I have to use the APP to withdraw and deposit funds. Isn't it a joke if I can't log in? There is also a website version that can't be found.
