*EDIT* - Resolved. When going into release notes and hitting the link to enable the bookmarks it took me to a different place to where I'd gone manually in the past.
My bad, and it's resolved.
@andrewilley Thanks for your reply - unfortunately the bookmark choice is not visible on my player at all, either with the long press or the 3 dots option.
I'm on 875-882. Any suggestions on what is going wrong?
Thanks,
Rob
