Most of the recent chapters on Pet King say they're unlocked ( mobile app) but if you look closer you will see that you need to watch an ad to unlock them ........ why ? I tried clearing cache but that didn't work
Unlocked chapters but not really unlocked

Also, have you tried on the website directly instead of the app?
I have also encountered the same problem while accessing new chapters in various Novels. So, I can say that the problem is not in the novel Pet King but in the System.
There is another problem similar to this, when I access the latest chapter of any novel let's say chapter 140 which requires stones or ad to be used but I access that chapter after a week even then also it requires me to do the same (After the week the chapter count has reached say 156) and I haven't read that novel for the whole week.(Got engrossed in another novel)
