Storytel in the new app

In the new Sonos app:

I can’t search for an unread book on Storytel. It’s always “no result”.

Every book I turn on (Storytel) starts from the beginning.

Can I change the setting somewhere so it will continue from where I am in the book or is this a bug?

I can’t access the function “categories” on Storytel.
Is there a setting for this?

(I had no problem with any of this functions in the old app)
