An issue with EPUB viewing

This app is generally very good, but one issue has been annoying me since I started using it. Namely, if I’m reading an epub file, whenever I exit the document and then re-enter the document, or sometimes the screen is turned off for a while and I resume reading, I always jump to the very beginning of the section I’m reading. I have to scroll all the way back to where I was reading. If the section I’m reading happens to be long, it actually takes a while for me to relocate where I was. This issue doesn’t occur to some other e-book reader apps, like Apple Books. I hope the developer can fix this issue in the future.
