Looks like there isn't a dedicated corrections topic, so here's the only typo I picked up while speeding through the first 4 chapters:
Chapter 1, page 15: "They've gotta be the stronest party around for sure." < strongest.
Seems like a decent adaptation of the light novel, so far. I think I'll stick to the prepubs of the manga as well, if I remember to (the fact they don't show up in the app doesn't help with my routine, though).
