To cover a topic i have seen complained a out a few times
Relocked chapters after subscription ended. We knew it would happen. It was in the subscription details... So. Pro tip. Should have downloaded the full novel during subscription duration. As offline all those chapters will be available (i dow7nloaded 3000 chapters over a few novels) and they are still unlocked during offline
But. The main point. I am only using this app as a catalog of novels i am/want to read and their update periods, i read them elsewhere now, except 1 which is exclusive to webnovel, i can use the daily SS to read it with its 1ch/2day update
