Perhaps it was because the version of the novel reading software on the phone was not perfect enough, or the screen size and resolution of the phone were not high enough to clearly display the content of the next page. It could also be because the phone's browser didn't support the page flipping function. He needed to use another browser or download a browser extension that supported the page flipping function. If you still can't turn the page, you can try to restart your phone or update the software version of the novel.
