Hello, I am using an iPhone 7 128 GB. I have attached a screenshot. You can see the black banner on top. When I drag it down it doesn't respond to bring up a quick reply keyboard. But it does move upwards to be dismissed. Clicking the banner opens up the message window. Used to work fine before but not functioning for a couple of days. I tried restarting my device but no use. I have also tried resetting all settings but still nothing is fixed. Any other possible fix without hard resetting the phone? I am on on the latest version of iOs10. Tried contacting whatsapp but no reply. Kindly assist. Thank You.
