Unexpectedly unusable – Xmind - Mind Map & Brainstorm Review

I’ve used XMind for years and have always loved it. I was excited to get this app so I can have more access and work on mindmaps while I’m on the road and at conferences. Unfortunately I can’t figure out how to even open a mindmap, let alone do anything with the app at all. So far it’s 100% unusable for me. I’m on a 7S with the latest versions of everything. I know others are using this successfully. I must be missing something but I have no idea what it is. I’d love to get a response from support but so far after almost a week, nothing.
