I am on the phone with Delstar now. The gentleman I spoke with said the update should be posted by morning at the very latest - they anticipate it will be posted today and he also made a video to help users that will be posted.
The upgrade should address the PDF and a text issue. My rotate button doesn't always work and it will address that as well. He also believes the upgrade will correct the formatting issues. He just checked a book he downloaded from Gutenberg and it had correcting formatting on his device for bold, underlining etc.
He is interested in assisting in any way he can and asked for the link to this forum. I'm sending him a link so you should expect to see him here to help!
