If the button isn’t there (it isn’t for me either);
- From the home screen, tap on ‘Help’
- In the Help Search box, type ‘in-app chat’ and enter
- A list of possibles, including ‘Contacting support’ should be shown - tap on it
- The Contacting support details are shown. In the section ‘Chat with us’, tap on ‘chat with us in the app’
Happy chatting!
