Can't get to this site's home page
Hello, this is my first post apart from the introduction. My experience of the site has been very frustrating so far ... I have the site's app, but it does not open on the home page, and offers no navigation tool to get there so far as I can see, no Home button or anything else. I have only been able to get here via links in posts. I've been to Help, Settings, it's just hopeless. I went to Settings on my iPad, but the app isn't even listed there, although it is installed and I am using it.
