Hmm. Well, if you were worried it could have been a fishing site of sorts, it doesn't seem to be. And it does feature extra chapters up to 92 (so far I've been reading it on Batoto that only has 64 chapters with two more added every week).
HOWEVER, manga41 likes to cut webtoons into pages, so there's no longstrip option at all, just 60 separate images.
I'm at a bit of a loss tbh, it does seem tempting to binge through ~30 extra chapters...
