My old phone is not available. I did delete and reload WA which did not solve the problem. Neither did turning my iphone on/off. I need WA for work. Please resolve this issue.
We never want you to miss any of your messages. I personally keep in touch with everyone through messaging myself, so I understand the importance of getting this problem fixed right away. Just so we are all on the same page when you say WA are you referring to WhatsApp? When did this issue start? What happens when you try using the messaging application that came preinstalled on the phone?
