I am facing some serious trouble with WhatsApp Login, I just now got my new iPhone 7 Plus and before that, I used to use Samsung S6, now the problem is that my WhatsApp is not working in the old phone and I am not even able to use it in iPhone. This is very complex and no solution is available on the internet, anyone here who can help me with this?
