Hi! When I am tracking my progress in a book, I use pages instead of percentage. In the past, when I've clicked into the "Track Progress" button to update, Storygraph will preserve my previous selection of pages (and I believe also showed the amount of pages I last tracked).
However, recently, it's been defaulting to % read each time (see screenshot), so I have to go through some extra clicks to select pages, then enter my progress each time. I definitely preferred the previous behavior, where I only had to make that selection once per book.
For troubleshooting- I am accessing Storygraph via the app on my Samsung Galaxy S22 (android) phone.
