This situation could be because the electronic device or software used when reading novels did not support changing the font size, or there would be some technical problems when flipping the pages, resulting in the font size and the flipping effect not being accurately achieved. In some novel reading applications, you can try adjusting the font size and zooming options to see if you can change the font size and adapt it to your reading habits. However, please note that some applications may not support all font and font sizes, so you may need to check the application's settings or documents to see how a particular application supports it. If you are using an electronic device such as a computer or tablet, you can try using different reading applications or browser to see if there are any problems with specific applications or settings. Some devices may not support changing the font size, so you may need to check the device manual or technical support to understand the available functions of a particular device.
