I’m using the current version of Komic 1.22.1 and current version of Komga. This happens on my iPhone and iPad running iOS 26.3When I get to the end of a book it gives me the option to open the next book as expected. I have the default timer length of 8 seconds. If I push the button to open the next chapter sooner than 8 seconds then on the next book, swipe gestures will not work. If I let the timer run out and advance to the next book then swipes work. I’ve had to close the book and re open it to get swipes to work again.
