Please try link on a post. It points to updated version. I assume you are using Android and if you try link on post you will see that it is latest release and haven't been announced yet 😊 We will announce all changes and explain each new feature in separate posts.

I installed it from the link on this post, but it says 'missing posting authority' when I try to reply.

Interesting, so you logging in with regular login method (not steemconnect). And you are using your posting private key, is that correct? I see that you made your last post from mobile app which means it should be working. Helps us to reproduce this issue, what you did or how did you get this issue, did you enable/disable pin code or did you logout and login or added different accounts, etc.
