From the forum:
I told my husband about the problem, he read what people advised me, then he also tried to throw the books but Kobo was hanging and didn't react to anything, the husband then pressed from behind with a clamp, according to the instructions, it was written.
WOW: It is not fair! Reading instructions is not sporty! Problems should be solved intuitively on the forum, preferably with those who have never seen this device in their eyes. Your husband ruined your pleasure.
