when you go to upload a chapter how long does it usually take to update?

Depends, usually 1 -2 hours average

Another person who asked that as well has to wait like 7 or so hours doeeee so yeah, kinda depends on the moderators and maybe how many reports they received that day (￣∇￣")

If you're talking abt the notifications, I think they notify you at a specific time each day. Though I'm not sure since I don't pay attention to it and the time set is in a different time zone than mine
