Since I came back to my ebook for college I saw the web app had an update, so I refreshed the page with that link at the bottom right of the screen. Now Ctrl-F search functionality is broken! I tried on my main browser Firefox and in MS Edge. I can see a word on the screen in my ebook and I Ctrl-F that search term and it says no results found. Literally no search terms appear through that search. The built-in web browser search is useless for what I was trying to search for, so - was this intentional? Is it a bug?
