I really can't figure out why this is happening. Whenever I try to change the font size on the Kindle 10th gen (not paperwhite) by pinching the screen, the dialog box appears as usual showing me the levels of the font size that I can adjust. But once I'm done, I am not able to refresh the screen to continue reading the book. I am forced to restart the device. Can someone help me fix this issue? Thanks a lot!
P.S. : My device is running firmware version : Kindle 5.12.5-April 2020
