Facing Issues with WhatsApp Login

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?

Problem is you got an iPhone. Android is much better.

The big question is whether you meant ‘LingQ app’ instead of ‘WhatsApp’…

You do one thing try to uninstall and then reinstall again. Hope this will help you.
