We have detected a technical issue linked to certain keyboard apps on Samsung and Huawei phones. Are you using either of these? Unfortunately, it's not possible to use these keyboards to type on our app. We do apologize for the inconvenience. As we're working on it to fix this issue, please try to use other keyboards available (as, for example, SwiftKey or OpenBoard). Please see links to download these below:
